Chemical Structure
Description
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.
CATO supplies 5,6-Diamino-2,4-dihydroxypyrimidine HCl salt (CAS 3240-72-0), a certified reference material (molecular formula C4H8N4O2, MW 144.13 g/mol) for analytical method development and quality control.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 5,6-Diamino-2,4-dihydroxypyrimidine HCl salt is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.13 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).
CATO manufactures 5,6-Diamino-2,4-dihydroxypyrimidine HCl salt 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.
