Irbesartan (CAS NO : 138402-11-6)

Irbesartan (CAS 138402-11-6) represents a cornerstone of the global API intermediates market, functioning as a potent, non-peptide angiotensin II receptor antagonist primarily indicated for the management of hypertension and diabetic nephropathy. The 2-butyl-3-[[2'-(1H-tetrazol-5-yl)[1,1'-biphenyl]-4-yl]methyl]-1,3-diazaspiro[4.4]non-1-en-4-one derivative has seen a surge in demand as a high purity fine chemical, particularly as CDMOs focus on optimized synthetic routes that mitigate the formation of mutagenic impurities like nitrosamines to satisfy rigorous EMA and FDA safety mandates. As a leading bulk chemical supplier, the shift toward localized, resilient supply chains has emphasized the need for custom synthesis services that can deliver consistent crystalline forms and particle size distributions required for blockbuster generic formulations (Pharma/API purity 99% | General Industry purity 98%). We are an established Irbesartan api supplier with >= 99% purity globally for semi-finished formulators, providing comprehensive analytical (HPLC/NMR/MS) and supporting Irbesartan COA/TDS/SDS region-specific regulatory support. reliable lead times, worldwide supply chain capabilities
