Montelukast 1,2-Diol (Mixture of Diastereomers) CAS 186352-97-6

Description

Compared with other compounds in its class, the molecular weight of 602.18 g/mol gives Montelukast 1,2-Diol (Mixture of Diastereomers) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Montelukast 1,2-Diol (Mixture of Diastereomers) (CAS 186352-97-6), molecular formula C35H36ClNO4S and molecular weight 602.18 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, Montelukast 1,2-Diol (Mixture of Diastereomers) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 602.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

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.
