Chemical Structure
Description
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Rosiglitazone Impurity 6 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 325.45 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.
CATO supplies Rosiglitazone Impurity 6 (CAS CATO-C4X-21796), a pharmacopoeial impurity reference standard (molecular formula C20H27N3O, MW 325.45 g/mol) used for the identification and quantification of trace impurities in APIs.
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 Rosiglitazone Impurity 6 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.
