Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 372.58 g/mol gives Orlistat Impurity 25 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Orlistat Impurity 25 (CAS CATO-C4X-149925) is a certified pharmaceutical impurity reference standard with the molecular formula C22H44O4 and a molecular weight of 372.58 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Orlistat Impurity 25 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 372.58 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures Orlistat Impurity 25 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.
