Chemical Structure

Argatroban Impurity 97 CAS CATO-C4X-100797 chemical structure

Description

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 supplies Argatroban Impurity 97 (CAS CATO-C4X-100797), a pharmacopoeial impurity reference standard (molecular formula C16H21NO8S, MW 387.40 g/mol) used for the identification and quantification of trace impurities in APIs.

Argatroban Impurity 97 (C16H21NO8S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO manufactures Argatroban Impurity 97 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.
