Chemical Structure

4-(2-Mercapto-4,4-dimethylpyrimidin-1(4H)-yl)-3-methoxybenzoic acid CAS 1142198-83-1 chemical structure

Description

As a certified reference material (CRM), 4-(2-Mercapto-4,4-dimethylpyrimidin-1(4H)-yl)-3-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.

4-(2-Mercapto-4,4-dimethylpyrimidin-1(4H)-yl)-3-methoxybenzoic acid (CAS 1142198-83-1) is a high-purity analytical reference standard with the molecular formula C14H16N2O3S and a molecular weight of 292.35 g/mol.

The molecular framework of 4-(2-Mercapto-4,4-dimethylpyrimidin-1(4H)-yl)-3-methoxybenzoic acid (C14H16N2O3S) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
