Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-Methyloxazolo[5,4-d]pyrimidin-7-amine.
2-Methyloxazolo[5,4-d]pyrimidin-7-amine (CAS 25680-37-9), molecular formula C6H6N4O and molecular weight 150.14 g/mol, is a CATO reference standard with documented purity and traceability.
2-Methyloxazolo[5,4-d]pyrimidin-7-amine (C6H6N4O) contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system. Its physicochemical properties are representative of its class; 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).
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.
