Chemical Structure
Description
CATO manufactures Bimatoprost Impurity 19 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
As a process- or degradation-related impurity, Bimatoprost Impurity 19 (CAS 41639-71-8, C23H32O5) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Structurally, Bimatoprost Impurity 19 (C23H32O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 388.50 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
