4-bromo-3-fluorobenzene-1-sulfonyl fluoride CAS 935534-33-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-bromo-3-fluorobenzene-1-sulfonyl fluoride.

4-bromo-3-fluorobenzene-1-sulfonyl fluoride (CAS 935534-33-1) is a high-purity analytical reference standard with the molecular formula C6H3BrF2O2S and a molecular weight of 257.05 g/mol.

Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine/bromine substitution, an aromatic ring system, 4-bromo-3-fluorobenzene-1-sulfonyl fluoride is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.05 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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-bromo-3-fluorobenzene-1-sulfonyl fluoride 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.
