Carglumic Acid Impurity 3 CAS 98-79-3

Description

Compared with other compounds in its class, the molecular weight of 129.11 g/mol gives Carglumic Acid Impurity 3 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Carglumic Acid Impurity 3 (CAS 98-79-3), a pharmacopoeial impurity reference standard (molecular formula C5H7NO3, MW 129.11 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Carglumic Acid Impurity 3 (C5H7NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 129.11 g/mol, it falls into the low-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 Carglumic Acid 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.
