2-(2,5-Dimethylphenylsulfonamido)-3-phenylpropanoic acid CAS 1449133-74-7

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(2,5-Dimethylphenylsulfonamido)-3-phenylpropanoic acid.

2-(2,5-Dimethylphenylsulfonamido)-3-phenylpropanoic acid (CAS 1449133-74-7), molecular formula C17H19NO4S and molecular weight 333.40 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 2-(2,5-Dimethylphenylsulfonamido)-3-phenylpropanoic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 333.40 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.

As a certified reference material (CRM), 2-(2,5-Dimethylphenylsulfonamido)-3-phenylpropanoic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
