The occurrence of Methyl 5-bromo-2-(1,1-dioxidoisothiazolidin-2-yl)benzoate is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 5-bromo-2-(1,1-dioxidoisothiazolidin-2-yl)benzoate (CAS 1373232-33-7) is a high-purity analytical reference standard with the molecular formula C11H12BrNO4S and a molecular weight of 334.19 g/mol.
The molecular framework of Methyl 5-bromo-2-(1,1-dioxidoisothiazolidin-2-yl)benzoate (C11H12BrNO4S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine 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), Methyl 5-bromo-2-(1,1-dioxidoisothiazolidin-2-yl)benzoate 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.
