2-(4-Methylphenylsulfonamido)-3-phenylpropanoic acid CAS 34635-34-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(4-Methylphenylsulfonamido)-3-phenylpropanoic acid.

2-(4-Methylphenylsulfonamido)-3-phenylpropanoic acid (CAS 34635-34-2) is a high-purity analytical reference standard with the molecular formula C16H17NO4S and a molecular weight of 319.38 g/mol.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-(4-Methylphenylsulfonamido)-3-phenylpropanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 319.38 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.
