(3-Formylphenyl)methanesulfonyl chloride CAS 1196153-71-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3-Formylphenyl)methanesulfonyl chloride.

(3-Formylphenyl)methanesulfonyl chloride (CAS 1196153-71-5), molecular formula C8H7ClO3S and molecular weight 218.66 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (3-Formylphenyl)methanesulfonyl chloride (C8H7ClO3S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 218.66 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), (3-Formylphenyl)methanesulfonyl 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.
