2-Chloro-N-methyl-N-(2-oxo-2-(thiophen-2-yl)ethyl)acetamide (CAS 1353952-33-6) is a high-purity analytical reference standard with the molecular formula C9H10ClNO2S and a molecular weight of 231.70 g/mol.
2-Chloro-N-methyl-N-(2-oxo-2-(thiophen-2-yl)ethyl)acetamide (C9H10ClNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-Chloro-N-methyl-N-(2-oxo-2-(thiophen-2-yl)ethyl)acetamide 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.
