Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 261.73 g/mol gives n-[4-(2-chloroacetyl)phenyl]-n-methylmethanesulfonamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies n-[4-(2-chloroacetyl)phenyl]-n-methylmethanesulfonamide (CAS 851398-37-3), a certified reference material (molecular formula C10H12ClNO3S, MW 261.73 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, n-[4-(2-chloroacetyl)phenyl]-n-methylmethanesulfonamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 261.73 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures n-[4-(2-chloroacetyl)phenyl]-n-methylmethanesulfonamide under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
