Description
CATO supplies 2-(Methylsulfonyl)benzoyl chloride (CAS 49639-13-6), a certified reference material (molecular formula C8H7ClO3S, MW 218.66 g/mol) for analytical method development and quality control.
Based on its molecular formula C8H7ClO3S, 2-(Methylsulfonyl)benzoyl chloride contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 218.66 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-(Methylsulfonyl)benzoyl 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.
