Chemical Structure

3-[Isocyano-(toluene-4-sulfonyl)-methyl]-benzoic acid methyl ester CAS 1008771-33-2 chemical structure

Description

The occurrence of 3-[Isocyano-(toluene-4-sulfonyl)-methyl]-benzoic acid methyl ester is closely related to a flavonoid core, 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 3-[Isocyano-(toluene-4-sulfonyl)-methyl]-benzoic acid methyl ester (CAS 1008771-33-2), a certified reference material (molecular formula C17H15NO4S, MW 329.37 g/mol) for analytical method development and quality control.

Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 3-[Isocyano-(toluene-4-sulfonyl)-methyl]-benzoic acid methyl ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 329.37 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures 3-[Isocyano-(toluene-4-sulfonyl)-methyl]-benzoic acid methyl ester under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
