Chemical Structure
Description
The occurrence of 6-Heptadecyl-2-thioxo-2,3-dihydropyrimidin-4(1H)-one is closely related to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
6-Heptadecyl-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (CAS 56510-28-2) is a high-purity analytical reference standard with the molecular formula C21H38N2OS and a molecular weight of 366.60 g/mol.
6-Heptadecyl-2-thioxo-2,3-dihydropyrimidin-4(1H)-one (C21H38N2OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
