Montelukast Hydroxy CAS 679838-32-5

Description

Compared with other compounds in its class, the molecular weight of 602.18 g/mol gives Montelukast Hydroxy distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Montelukast Hydroxy (CAS 679838-32-5), molecular formula C35H36ClNO4S and molecular weight 602.18 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C35H36ClNO4S, Montelukast Hydroxy contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 602.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures Montelukast Hydroxy 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.
