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 (E)-1-(4-methyl-1,2,5-oxadiazol-3-yl)ethan-1-one oxime (CAS 212254-68-7), a certified reference material (molecular formula C5H7N3O2, MW 141.13 g/mol) for analytical method development and quality control.
The molecular framework of (E)-1-(4-methyl-1,2,5-oxadiazol-3-yl)ethan-1-one oxime (C5H7N3O2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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. 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).
CATO manufactures (E)-1-(4-methyl-1,2,5-oxadiazol-3-yl)ethan-1-one oxime 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.
