2-Butyl Valeric Acid (CAT. No. CP-V6014, CAS No. 3274-28-0), chemically designated as 2-Propylhexanoic acid, is a branched-chain fatty acid with molecular formula C9H18O2 and molecular weight 158.24 g/mol. Manufactured at Chemicea to stringent purity benchmarks, this compound is widely recognized as a key process-related impurity of Valproic Acid and finds application across analytical method development, method validation (AMV), and quality-control testing supporting ANDA filings and pharmacopeial (USP/EP) compliance. Beyond its role as a reference impurity standard, it also serves as a synthetic building block in the manufacture of flavour and fragrance esters, ester-based lubricants, and plasticiser intermediates. Every batch shipped from Chemicea is accompanied by a Certificate of Analysis (COA) with HPLC/GC-verified purity, ensuring analytical traceability for R&D use at mg to gram scale.
