Chemical Structure

4-Methylurazole CAS 16312-79-1 chemical structure

Description

CATO manufactures 4-Methylurazole 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.

4-Methylurazole (CAS 16312-79-1) is a high-purity analytical reference standard with the molecular formula C3H3N3O2 and a molecular weight of 113.07 g/mol.

Structurally, 4-Methylurazole (C3H3N3O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 113.07 g/mol, it falls into the low-molecular-weight range. 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.
