B-Butenonitrile, also known in the industry as crotononitrile, stands out as a C4 nitrile compound important for chemical synthesis and specialty intermediate applications. Its molecular formula, C4H5N, reveals a straightforward carbon-nitrogen structure with a density usually around 0.8 g/cm³. B-Butenonitrile’s CAS number is 623-13-2, making traceability straightforward on customs paperwork and material safety documentation. The material appears as a colorless to light yellow liquid, highlighting the need for careful storage and handling in raw material stockrooms.
HS Code 29269090 typically applies for customs classification, helping importers and distributors manage clearance without hitches. The compound forms part of both research and industrial production chains. It stands as a versatile building block within pharmaceutical intermediates, polymer additives, and solvent formulations, making it a staple on the sourcing plans of chemical buyers across the globe.
China has become a leading source for B-Butenonitrile, offering competitive factory price quotes and flexible supply solutions. Direct purchase from Chinese chemical manufacturers gives buyers access to ISO, SGS, halal, kosher certified product lots. Plenty of OEM contract manufacturers are ready to help import-export companies bring value-added formulations to market. For buyers, reaching out through channels like inquiry forms, MOQ negotiation, and quote submissions on Alibaba or Made-in-China speeds up procurement cycles. Factories often provide liter solution samples and accommodate small-scale orders for product qualification runs.
MSDS and SDS documentation travel with every shipment, reflecting strict compliance with China REACH policies and international regulatory frameworks. Buyers should always check for valid ISO certificates, third-party SGS testing, and TDS specifications to ensure the batch matches quality expectations and safety standards. Certifications like halal and kosher also support food, pharma, and global export requirements, expanding potential customer markets.
B-Butenonitrile carries health and safety risks like most nitriles. The chemical can act as a hazardous raw material — inhalation, ingestion, or skin contact can harm health, making PPE, good ventilation, and proper storage critical parts of workplace policy. Modern Chinese producers include SDS information and advice in every sale, but buyers must double-check that tanks, drums, and packages stay sealed and labeled. Removing the risk of leaks and spills starts with robust packaging and extends to regular warehouse checks.
Factories typically use aluminum or HDPE drums, chosen to resist the nitrile’s reactivity and to support safe shipping — whether by CIF, FOB, or direct delivery. Buyers should not cut corners with uncertified packaging; safe storage and rapid incident response keep workers healthy and protect assets.
Prices for B-Butenonitrile reflect both raw material volatility and logistical factors. China’s abundant feedstock and scale economies support stable, globally competitive pricing. Policy changes, especially around REACH and local environmental audits, can send ripples through the market — so it pays to keep an eye out for new news and regulatory updates.
Flexible MOQ terms open the door for both large corporations and smaller buyers to place timely orders as needed, be it a drum, pallet, or container load. For those looking to sample before purchase, many suppliers offer free or discounted test lots, making practical evaluation more available. Buyers should ask for fresh COA and retain a sample of every batch as a simple insurance step.
Getting dependable B-Butenonitrile supply hinges on relationships with factories that document every step, provide transparent safety info, and carry internationally recognized certifications. Buyers ready to act as partners — asking the right questions, filing thorough inquiries, and respecting local import policy — build chemical programs that deliver on both price and safety.
