The occurrence of Arotinolol Impurity 52 is closely related to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Arotinolol Impurity 52 (CAS CATO-C4X-185452), a pharmacopoeial impurity reference standard (molecular formula C15H20N2O5S3, MW 404.52 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Arotinolol Impurity 52 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 404.52 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 Arotinolol Impurity 52 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.
