Chemical Structure

Montelukast Impurity N6 CAS 66-40-0 chemical structure

Description

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.

CATO supplies Montelukast Impurity N6 (CAS 66-40-0), a pharmacopoeial impurity reference standard (molecular formula C8H20ClN, MW 165.70 g/mol) used for the identification and quantification of trace impurities in APIs.

Montelukast Impurity N6 (C8H20ClN) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures Montelukast Impurity N6 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.
