Minoxidil Impurity 6 CAS 116436-03-4 chemical structure

Description

CATO supplies Minoxidil Impurity 6 (CAS 116436-03-4), a pharmacopoeial impurity reference standard (molecular formula C6H10N4O, MW 154.17 g/mol) used for the identification and quantification of trace impurities in APIs.

Minoxidil Impurity 6 (C6H10N4O) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; 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).

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

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.
