Thioctic acid Impurity 78 CAS CATO-C4X-152678

Description

The occurrence of Thioctic acid Impurity 78 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Thioctic acid Impurity 78 (CAS CATO-C4X-152678), a pharmacopoeial impurity reference standard (molecular formula C12H24O4, MW 232.32 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Thioctic acid Impurity 78 (C12H24O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 232.32 g/mol, it falls into the medium-molecular-weight range. 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.

CATO manufactures Thioctic acid Impurity 78 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.
