Chemical Structure

Colesevelam Decyl Aminoquat Impurity HBr (6-Decylaminohexyl Trimethylammonium Bromide HBr) CAS 2247938-20-9 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 Colesevelam Decyl Aminoquat Impurity HBr (6-Decylaminohexyl Trimethylammonium Bromide HBr).

CATO supplies Colesevelam Decyl Aminoquat Impurity HBr (6-Decylaminohexyl Trimethylammonium Bromide HBr) (CAS 2247938-20-9), a pharmacopoeial impurity reference standard (molecular formula C19H43N2HBrBr, MW 460.38 g/mol) used for the identification and quantification of trace impurities in APIs.

Colesevelam Decyl Aminoquat Impurity HBr (6-Decylaminohexyl Trimethylammonium Bromide HBr) (C19H43N2HBrBr) contains bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
