Minoxidil Impurity 43 HCl CAS 1799434-61-9 chemical structure

Description

CATO manufactures Minoxidil Impurity 43 HCl 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.

CATO supplies Minoxidil Impurity 43 HCl (CAS 1799434-61-9), a pharmacopoeial impurity reference standard (molecular formula C5H9NHCl, MW 119.59 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to chlorine substitution, Minoxidil Impurity 43 HCl is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 119.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
