Chemical Structure

Dexmedetomidine Impurity 74 CAS CATO-C4X-123074 chemical structure

Description

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 supplies Dexmedetomidine Impurity 74 (CAS CATO-C4X-123074), a pharmacopoeial impurity reference standard (molecular formula C12H16O, MW 176.25 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a hydroxyl group, an ether linkage, an aromatic ring system, Dexmedetomidine Impurity 74 is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 176.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
