Addressing Purity and Supply Challenges in 4-Bromocrotonic Acid (CAS 13991-36-1) Procurement
Industrial chemists and manufacturers know the frustration of inconsistent raw material quality—fluctuating purity levels causing unexpected副反应, batch variations derailing research reproducibility, and delayed deliveries disrupting production schedules. Over our 10+ years in chemical supply, we've witnessed how these issues directly impact project timelines and operational costs for both large-scale manufacturers and research institutions.
A Stable and Reliable Chemical Supply Solution
Our 4-Bromocrotonic Acid CAS 13991-36-1 addresses these critical pain points with guaranteed 99% purity and a stable supply chain capable of fulfilling orders from kilogram to ton level. Backed by a large warehousing center and 20t/year production capacity, we ensure consistent availability even for bulk requirements, supporting uninterrupted manufacturing processes for chemical production enterprises and research facilities across 50+ countries.
Typical Industrial Applications
As a specialized Chemical Synthesis Raw Material, 4-Bromocrotonic Acid CAS 13991-36-1 plays a vital role in organic synthesis processes, serving as a key intermediate in the production of pharmaceuticals, agrochemicals, and specialty chemicals. Its unique brominated structure makes it particularly valuable for creating complex molecular architectures in industrial laboratories and manufacturing settings, where precision and reliability are paramount.
Why Key Specifications Matter
The 99% purity of our 4-Bromocrotonic Acid minimizes副反应 and impurity interference, ensuring cleaner synthesis outcomes and reducing purification costs. Its well-defined melting point (74℃) and boiling point (287.6±23.0 °c at 760 mmHg) provide consistent process parameters, critical for scaling reactions from lab to production. The solid state and standardized 25kg packing format facilitate safe handling and accurate dosing, while the verified molecular formula (C4h5bro2) guarantees structural consistency—essential for maintaining reaction specificity in multi-step synthesis workflows.
