Description
CATO manufactures 2-Ethyl-1,3-oxazole-4-carbonyl chloride 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.
CATO supplies 2-Ethyl-1,3-oxazole-4-carbonyl chloride (CAS 1858241-93-6), a certified reference material (molecular formula C6H6ClNO2, MW 159.57 g/mol) for analytical method development and quality control.
Based on its molecular formula C6H6ClNO2, 2-Ethyl-1,3-oxazole-4-carbonyl chloride contains an amide 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 159.57 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.
