Chemical Structure
Description
The occurrence of 5-Chloro-3-ethyl-1,2-oxazole is closely related to an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 5-Chloro-3-ethyl-1,2-oxazole (CAS 1314898-34-4), a certified reference material (molecular formula C5H6ClNO, MW 131.56 g/mol) for analytical method development and quality control.
The molecular framework of 5-Chloro-3-ethyl-1,2-oxazole (C5H6ClNO) is characterized by an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 5-Chloro-3-ethyl-1,2-oxazole 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.
