Pent-4-ynenitrile stands out for its unique triple bond and nitrile function. The structure, CH3C≡CCH2CN, brings a straightforward combination: a five-carbon backbone, an alkyne, and a nitrile group. This structure shapes its strong reactivity and appeals to specialty chemical supply chains, especially in the pharmaceutical and fine chemical industries. The molecular formula, C5H5N, gives a specific density near 0.88 g/mL at 25°C. Liquid at room temperature, Pent-4-ynenitrile can dissolve in a wide range of organic solvents but resists water. With its boiling point around 116°C and a pungent odor, anyone handling this raw material should pay extra attention to proper ventilation and PPE requirements listed in the SDS (safety data sheet).
China’s chemical market offers competitive pricing for Pent-4-ynenitrile due to large-scale manufacturing and stable raw material sourcing. Factory price negotiation usually moves around FOB Shanghai or CIF main ports, and many factories ensure quick turnaround for spot orders or custom quantity (MOQ) requirements. Certification matters when working with high-purity intermediates for pharmaceuticals or agrochemicals. Suppliers send out REACH, ISO, SGS, Kosher, and Halal certifications on request, and for importers, the HS Code 2926909090 figures in customs paperwork and policy compliance. Markets see fluctuating prices as raw material cost, fuel prices, and policy shifts all play a part in the quote you receive on any given day.
Pent-4-ynenitrile demands respect in an industrial space. The MSDS calls it hazardous due to its harmful vapor and skin contact risk. I remember running a pilot lot where extra exhaust fans cut exposure, and glove changes got more frequent compared to less volatile nitriles. Most suppliers provide a full SDS and sometimes a TDS. Laboratories and plants refer to these documents every day, and Chinese manufacturers who target export buyers supply up-to-date documentation in line with latest policy. Transport needs leak-proof drums and UN-approved packaging. Even a liter solution sets off a strong odor, so standard practice calls for respiratory protection and chemical splash goggles during filling or transfer steps. Safety doesn’t take a back seat.
In small quantities, Pent-4-ynenitrile serves as a building block for new chemical entities, especially in R&D and scale-up settings. Recent news sees interest jump from fine chemical makers and material science labs pushing new catalysts and organic electronics. Order inquiries often run small at first—1 kilogram, even 100 grams for new customers—and freight cost affects landed price, especially for orders below 20 kilograms. Many buyers now ask about free samples so they can check compatibility with their own process. Some companies ask for OEM packaging or special labeling to meet in-house tracking policies.
With more buyers now asking for halal and kosher certified raw materials, China-based suppliers respond by getting full documentation and cooperation from certification agencies. Global shipments seldom move without a stack of paperwork—COA, SDS, TDS, REACH registration, ISO 9001 details, and original signed certificates. Factories willing to train on REACH and product safety issues gain repeat customers. My own purchasing team starts from certification, then price, then delivery time. Skipping any of those steps shortchanges everyone—from importer to final user.
