Chemical Structure

4-Chloro-5-sulfamoylanthranilic Acid Methyl Ester CAS 3994-89-6 chemical structure

Description

The occurrence of 4-Chloro-5-sulfamoylanthranilic Acid Methyl Ester is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

4-Chloro-5-sulfamoylanthranilic Acid Methyl Ester (CAS 3994-89-6) is a high-purity analytical reference standard with the molecular formula C8H9ClN2O4S and a molecular weight of 264.69 g/mol.

The molecular framework of 4-Chloro-5-sulfamoylanthranilic Acid Methyl Ester (C8H9ClN2O4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. 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.

As a certified reference material (CRM), 4-Chloro-5-sulfamoylanthranilic Acid Methyl Ester 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.
