Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Nateglinide Impurity 3.
CATO supplies Nateglinide Impurity 3 (CAS 491828-09-2), a pharmacopoeial impurity reference standard (molecular formula C19H27NO3, MW 317.42 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, Nateglinide Impurity 3 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 317.42 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).
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.
CATO manufactures Nateglinide Impurity 3 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.
