Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies 2-(4-Methylphenyl)-4-(pyridin-4-yl)pyrimidine-5-carbohydrazide dihydrochloride (CAS 1046801-89-1), a certified reference material (molecular formula C17H17N5OCl, MW 342.81 g/mol) for analytical method development and quality control.
2-(4-Methylphenyl)-4-(pyridin-4-yl)pyrimidine-5-carbohydrazide dihydrochloride (C17H17N5OCl) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point; 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
