Chemical Structure
Description
CATO manufactures 1-Hydroxy-1,3-dihydro-2H-imidazol-2-one 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 1-Hydroxy-1,3-dihydro-2H-imidazol-2-one (CAS 116451-44-6), a certified reference material (molecular formula C3H4N2O2, MW 100.08 g/mol) for analytical method development and quality control.
1-Hydroxy-1,3-dihydro-2H-imidazol-2-one (C3H4N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
