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 Sotagliflozin Impurity 2.
CATO supplies Sotagliflozin Impurity 2 (CAS 1327165-94-5), a pharmacopoeial impurity reference standard (molecular formula C21H25ClO7, MW 424.87 g/mol) used for the identification and quantification of trace impurities in APIs.
Sotagliflozin Impurity 2 (C21H25ClO7) contains a flavonoid core, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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).
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
