(S)-2-(3-Oxobenzo[d]isothiazol-2(3h)-yl)-2-phenylacetic acid CAS 1217696-23-5

Description

The occurrence of (S)-2-(3-Oxobenzo[d]isothiazol-2(3h)-yl)-2-phenylacetic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (S)-2-(3-Oxobenzo[d]isothiazol-2(3h)-yl)-2-phenylacetic acid (CAS 1217696-23-5), a certified reference material (molecular formula C15H11NO3S, MW 285.32 g/mol) for analytical method development and quality control.

The molecular framework of (S)-2-(3-Oxobenzo[d]isothiazol-2(3h)-yl)-2-phenylacetic acid (C15H11NO3S) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
