6-Amino-5-isopropyl-1,3-dimethylpyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione CAS 1443288-33-2

Description

The occurrence of 6-Amino-5-isopropyl-1,3-dimethylpyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-Amino-5-isopropyl-1,3-dimethylpyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione (CAS 1443288-33-2), molecular formula C12H16N4O2 and molecular weight 248.28 g/mol, is a CATO reference standard with documented purity and traceability.

6-Amino-5-isopropyl-1,3-dimethylpyrido[2,3-d]pyrimidine-2,4(1H,3H)-dione (C12H16N4O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
