Chemical Structure

3-Acetyl-5-chlorothiophene-2-boronic acid CAS 1451390-79-6 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 3-Acetyl-5-chlorothiophene-2-boronic acid.

3-Acetyl-5-chlorothiophene-2-boronic acid (CAS 1451390-79-6), molecular formula C6H6BClO3S and molecular weight 204.44 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3-Acetyl-5-chlorothiophene-2-boronic acid (C6H6BClO3S) is characterized by a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), 3-Acetyl-5-chlorothiophene-2-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.
