Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 1-(2-Chlorooxazol-4-yl)ethanone (CAS 1393545-62-4), a certified reference material (molecular formula C5H4ClNO2, MW 145.54 g/mol) for analytical method development and quality control.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, 1-(2-Chlorooxazol-4-yl)ethanone is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 1-(2-Chlorooxazol-4-yl)ethanone 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.
