Chemical Structure

3-(Isopropylthio)-4-methoxybenzoic acid CAS 159783-12-7 chemical structure

Description

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

CATO supplies 3-(Isopropylthio)-4-methoxybenzoic acid (CAS 159783-12-7), a certified reference material (molecular formula C11H14O3S, MW 226.29 g/mol) for analytical method development and quality control.

3-(Isopropylthio)-4-methoxybenzoic acid (C11H14O3S) 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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), 3-(Isopropylthio)-4-methoxybenzoic 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.
