Chemical Structure
Description
CATO supplies 5,6-Diamino-2,4-dihydroxypyrimidine-13C2, Hydrochloride Salt (CAS 1346605-20-6), a certified reference material (molecular formula C4H6N4O2HCl, MW 178.58 g/mol) for analytical method development and quality control.
Based on its molecular formula C4H6N4O2HCl, 5,6-Diamino-2,4-dihydroxypyrimidine-13C2, Hydrochloride Salt contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 178.58 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
