Chemical Structure
Description
2-Methyl-2H-thiazolo[3,2-a]pyrimidin-5(3H)-one (CAS 41200-23-1), molecular formula C12H7F15O2 and molecular weight 468.16 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, 2-Methyl-2H-thiazolo[3,2-a]pyrimidin-5(3H)-one is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 468.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
