Chemical Structure

[4-(Isopropylsulfonyl)phenyl]acetic acid CAS 1105193-73-4 chemical structure

Description

The occurrence of [4-(Isopropylsulfonyl)phenyl]acetic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies [4-(Isopropylsulfonyl)phenyl]acetic acid (CAS 1105193-73-4), a certified reference material (molecular formula C11H14O4S, MW 242.29 g/mol) for analytical method development and quality control.

[4-(Isopropylsulfonyl)phenyl]acetic acid (C11H14O4S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
