Chemical Structure
Description
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 7-Hydroxy-3-methyl-5-oxo-N-propyl-5H-thiazolo[3,2-a]pyrimidine-6-carboxamide is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 267.30 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).
7-Hydroxy-3-methyl-5-oxo-N-propyl-5H-thiazolo[3,2-a]pyrimidine-6-carboxamide (CAS 898412-38-9) is a high-purity analytical reference standard with the molecular formula C11H13N3O3S and a molecular weight of 267.30 g/mol.
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.
