Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Chloro-N-methyl-N-(2-oxo-2-(p-tolylamino)ethyl)propanamide (CAS 857041-78-2), molecular formula C13H17ClN2O2 and molecular weight 268.74 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C13H17ClN2O2, 2-Chloro-N-methyl-N-(2-oxo-2-(p-tolylamino)ethyl)propanamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 268.74 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 2-Chloro-N-methyl-N-(2-oxo-2-(p-tolylamino)ethyl)propanamide 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.
