Ethyl 4-(4-bromophenyl)sulfonylbenzoate CAS 141212-53-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 4-(4-bromophenyl)sulfonylbenzoate.

CATO supplies Ethyl 4-(4-bromophenyl)sulfonylbenzoate (CAS 141212-53-5), a certified reference material (molecular formula C15H13BrO4S, MW 369.23 g/mol) for analytical method development and quality control.

Ethyl 4-(4-bromophenyl)sulfonylbenzoate (C15H13BrO4S) contains a flavonoid core, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 4-(4-bromophenyl)sulfonylbenzoate 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.
