Description

CATO manufactures 3-(4-Chlorophenyl)-2H-oxazolo[3,2-a][1,3,5]triazine-2,4(3H)-dione 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.

3-(4-Chlorophenyl)-2H-oxazolo[3,2-a][1,3,5]triazine-2,4(3H)-dione (CAS 35629-63-1) is a high-purity analytical reference standard with the molecular formula C11H6ClN3O3 and a molecular weight of 263.64 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 3-(4-Chlorophenyl)-2H-oxazolo[3,2-a][1,3,5]triazine-2,4(3H)-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 263.64 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
