Methyl ((4-methoxyphenyl)sulfonyl)alaninate CAS 85622-75-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Methyl ((4-methoxyphenyl)sulfonyl)alaninate.

CATO supplies Methyl ((4-methoxyphenyl)sulfonyl)alaninate (CAS 85622-75-9), a certified reference material (molecular formula C11H15NO5S, MW 273.31 g/mol) for analytical method development and quality control.

The molecular framework of Methyl ((4-methoxyphenyl)sulfonyl)alaninate (C11H15NO5S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
