Chemical Structure

Potassium (E)-4-(4-methoxystyryl)pyrimidine-2-thiolate CAS 318248-58-7 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

Potassium (E)-4-(4-methoxystyryl)pyrimidine-2-thiolate (CAS 318248-58-7) is a high-purity analytical reference standard with the molecular formula C13H11N2OSK and a molecular weight of 282.40 g/mol.

Potassium (E)-4-(4-methoxystyryl)pyrimidine-2-thiolate (C13H11N2OSK) contains a nitrogen-containing heterocyclic scaffold, 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.

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.
