Chemical Structure
Description
7-Benzyl-3-methyl-8-(piperazin-1-yl)-3,7-dihydro-1h-purine-2,6-dione (CAS 299419-33-3), molecular formula C17H20N6O2 and molecular weight 340.38 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 7-Benzyl-3-methyl-8-(piperazin-1-yl)-3,7-dihydro-1h-purine-2,6-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 340.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
