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-5-chloro-2-thienyl)boronic acid.
CATO supplies (4-bromo-5-chloro-2-thienyl)boronic acid (CAS 1150114-72-9), a certified reference material (molecular formula C4H3BBrClO2S, MW 241.30 g/mol) for analytical method development and quality control.
Structurally, (4-bromo-5-chloro-2-thienyl)boronic acid (C4H3BBrClO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.5, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 241.30 g/mol, it falls into the medium-molecular-weight range. 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), (4-bromo-5-chloro-2-thienyl)boronic acid 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.
