Cyclopropanecarbonyl Chloride is a high-value acyl chloride intermediate used when you need a compact cyclopropyl “building block” that reacts cleanly and fast in synthesis. In real production, the difference between a lab-ready reagent and a factory-ready intermediate is not the reaction itself—it’s the repeatability: consistent identity, controlled moisture exposure, and packaging that arrives the same way it left the plant.
Designed for B2B procurement: R&D scale-up, pilot production, and routine manufacturing supply
Ideal when your process needs rapid acylation and dependable conversion
Supplied with documentation options that help shorten your internal approval cycle (COA/SDS/packing and traceability support)

Picture opening a sealed container and noticing the sharp, “reactive” character typical of acyl chlorides—this is the moment chemists recognize they’re working with a serious intermediate, not a diluted commodity. Cyclopropanecarbonyl Chloride is commonly described as a colorless to pale yellow liquid and is chosen because its cyclopropyl group delivers a compact steric profile while still enabling strong downstream performance in target molecules.
The story behind why buyers keep this material on their approved list is simple: when timelines are tight, you don’t want to fight impurities, inconsistent identity, or moisture damage. A reliable supply of cyclopropanecarbonyl chloride helps your team keep reactions predictable—so the discussion stays on yield and selectivity, not on rework and waste.
For purchasing teams, this product is best evaluated by three practical questions:
Can you verify identity quickly (CAS/EINECS/formula/MW)?
Can the supplier protect it from moisture during packing and shipping?
Can you get batch-level documentation that matches your audit needs?
Instead of listing generic “functions,” here is what matters operationally for B2B customers—how this product protects your schedule and process stability:
Fast-reacting acyl chloride profile
Helps reduce reaction time windows and supports efficient acylation pathways in development and production.
Moisture-risk awareness built into supply practices
This substance is noted as reacting violently with water, and moisture exposure can generate hydrogen chloride—so packaging integrity and dry handling are not optional.
Clear identity for procurement and registration
A clean identity set (CAS/EINECS/formula/MW) simplifies internal approvals and cross-team communication.
Scale-friendly sourcing
Suitable for customers who may start with small batches for validation and later require stable, repeating supply lots.
Process-minded consistency
Helps reduce batch-to-batch troubleshooting so your chemists can focus on synthesis outcomes rather than input variability.
Cyclopropanecarbonyl chloride is widely positioned as an organic synthesis intermediate used to introduce a cyclopropylcarbonyl group into downstream molecules. In practice, buyers typically source it for:
Pharmaceutical and fine chemical intermediates where the cyclopropyl motif is used to tune potency, selectivity, or metabolic stability
Agrochemical and specialty chemical synthesis requiring compact ring structures
R&D to pilot scale-up projects where reaction speed and reproducibility are valued
Custom synthesis routes that prefer acyl chlorides for efficient coupling chemistry
Because this chemistry is sensitive to water, the application value is not only reactivity—it’s control. When the material arrives dry, sealed, and consistently identified, it becomes a dependable “reaction starter.” When it arrives compromised, it becomes a project delay. That’s why B2B buyers often evaluate the supplier’s packaging discipline and documentation as seriously as the raw reagent itself.
This product should be treated as a moisture-sensitive, reactive acyl chloride. Market-standard safety references emphasize that it can be flammable, may cause severe burns, and reacts violently with water. For B2B handling, the most useful guidance is operational:
Keep it dry and tightly sealed
Moisture exposure can decompose the material and generate acidic byproducts such as hydrogen chloride.
Use appropriate ventilation and PPE
Focus on preventing vapor exposure and contact events in routine transfer operations.
Temperature control
Common commercial references often indicate cool storage conditions (frequently low single-digit °C ranges for longer-term stability), depending on packaging and your internal SOP.
Good practice for receiving inspection
Check container seal integrity, label clarity, and batch identification before moving to controlled storage.
If your organization uses stricter internal EHS rules (pharma, regulated manufacturing), we support aligning shipment documentation to your site’s receiving and quarantine requirements.
For B2B procurement, “packaging” is not an afterthought—it is the product’s stability plan. Because cyclopropanecarbonyl chloride is moisture-sensitive, packaging must protect against humidity swings, transit vibration, and repeated handling at customs or warehouses.
Packaging options
Common export patterns for reactive intermediates include small bottles for evaluation and larger industrial packs for production, using chemical-compatible containers and secure closures.
Labeling and traceability
Each shipment can be aligned with batch/lot identifiers, product name and synonyms, and required hazard communication elements based on destination rules.
Export readiness
We can coordinate packing lists, gross/net weight details, and transport-safe outer cartons so your forwarder has fewer questions—and your receiving team has fewer delays.
Shelf-life and storage communication
We clearly communicate storage expectations and handling precautions so the product arrives ready to use, not ready to argue about.

B2B buyers don’t just buy a chemical—they buy confidence that the shipment can pass receiving inspection, internal audit, and process validation. We support that with a documentation mindset:
Batch-level documentation
COA options tied to lot/batch identity, plus supporting test items as needed by your QC framework.
Safety documentation
SDS availability to support transport, storage, and onsite risk assessments. Industry SDS sources emphasize moisture reactivity and corrosive risk, reinforcing why packaging and dry handling are critical.
Traceability support
Clear labeling and batch mapping help reduce disputes and simplify any downstream investigation.
Procurement support
We can help you prepare a supplier qualification package: product identity, recommended storage conditions, and documentation checklist aligned to your buyer’s SOP.
This approach strengthens E-E-A-T: it shows we understand how purchasing, QA, and production teams actually use product information in the real world.
Choosing a supplier for a reactive intermediate is choosing a partner for your workflow, not just a line item.
We prioritize stability, not shortcuts
Moisture-sensitive products fail quietly—until your reaction fails loudly. Our supply approach is built around protecting product integrity during packing, warehousing, and transit.
B2B communication that matches technical reality
We provide clear identity parameters, batch traceability support, and documentation options that reduce back-and-forth with your QA team.
Flexible order scenarios
From evaluation quantities to repeating production orders, we support scaling without forcing you to re-qualify a new source at each stage.
Responsiveness for technical buyers
If your chemist needs a specific purity target, packaging preference, or documentation set, we treat it as part of the procurement solution—not an inconvenience.
