Chemical Structure
Description
Owing to an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 2-Hydroxy-4-methylpyrimidine Hydrochloride is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 146.57 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).
2-Hydroxy-4-methylpyrimidine Hydrochloride (CAS 5348-51-6), molecular formula C5H6N2OHCl and molecular weight 146.57 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
