4-Bromo-2-cyano-5-(hydroxymethyl)benzene-1-sulfonyl chloride CAS 1805550-22-4 chemical structure

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-2-cyano-5-(hydroxymethyl)benzene-1-sulfonyl chloride.

CATO supplies 4-Bromo-2-cyano-5-(hydroxymethyl)benzene-1-sulfonyl chloride (CAS 1805550-22-4), a certified reference material (molecular formula C8H5BrClNO3S, MW 310.55 g/mol) for analytical method development and quality control.

Structurally, 4-Bromo-2-cyano-5-(hydroxymethyl)benzene-1-sulfonyl chloride (C8H5BrClNO3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 310.55 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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-2-cyano-5-(hydroxymethyl)benzene-1-sulfonyl chloride 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.
