Chemical Structure

methyl 2-(chlorosulfonyl)-3-nitrobenzoate CAS 1864061-83-5 chemical structure

Description

The molecular framework of methyl 2-(chlorosulfonyl)-3-nitrobenzoate (C8H6ClNO6S) 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).

methyl 2-(chlorosulfonyl)-3-nitrobenzoate (CAS 1864061-83-5) is a high-purity analytical reference standard with the molecular formula C8H6ClNO6S and a molecular weight of 279.65 g/mol.

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), methyl 2-(chlorosulfonyl)-3-nitrobenzoate 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.
