Arotinolol Impurity 55 CAS CATO-C4X-185455

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Arotinolol Impurity 55.

CATO supplies Arotinolol Impurity 55 (CAS CATO-C4X-185455), a pharmacopoeial impurity reference standard (molecular formula C11H11ClN2O3S3, MW 350.86 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Arotinolol Impurity 55 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 350.86 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 55 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.
