Chemical Structure

n-(5-Chlorothiophen-2-yl)methanesulfonamide CAS 1179660-71-9 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 n-(5-Chlorothiophen-2-yl)methanesulfonamide.

n-(5-Chlorothiophen-2-yl)methanesulfonamide (CAS 1179660-71-9) is a high-purity analytical reference standard with the molecular formula C5H6ClNO2S2 and a molecular weight of 211.69 g/mol.

n-(5-Chlorothiophen-2-yl)methanesulfonamide (C5H6ClNO2S2) contains an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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), n-(5-Chlorothiophen-2-yl)methanesulfonamide 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.
