Chemical Structure

Ritlecitinib impurity 2 CAS 1799311-98-0 chemical structure

Description

CATO manufactures Ritlecitinib impurity 2 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.

CATO supplies Ritlecitinib impurity 2 (CAS 1799311-98-0), a pharmacopoeial impurity reference standard (molecular formula C11H22N2O2, MW 214.30 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Ritlecitinib impurity 2 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 214.30 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.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
