Chemical Structure
Description
Ethyl 2-((4-bromophenyl)sulfonyl)acetate (CAS 30749-64-5), molecular formula C10H11BrO4S and molecular weight 307.16 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 2-((4-bromophenyl)sulfonyl)acetate (C10H11BrO4S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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), Ethyl 2-((4-bromophenyl)sulfonyl)acetate 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.
