Description
Compared with other compounds in its class, the molecular weight of 328.32 g/mol gives 1,3-Dimethyl-7-(phenoxymethyl)-6,7-dihydrooxazolo[2,3-f]purine-2,4(1H,3H)-dione distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1,3-Dimethyl-7-(phenoxymethyl)-6,7-dihydrooxazolo[2,3-f]purine-2,4(1H,3H)-dione (CAS 78960-54-0), molecular formula C16H16N4O4 and molecular weight 328.32 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, 1,3-Dimethyl-7-(phenoxymethyl)-6,7-dihydrooxazolo[2,3-f]purine-2,4(1H,3H)-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 328.32 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
