Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(Benzylthio)-4-(4-methoxyphenoxy)thieno[3,2-d]pyrimidine (CAS 478067-47-9) is a high-purity analytical reference standard with the molecular formula C20H16N2O2S2 and a molecular weight of 380.48 g/mol.
The molecular framework of 2-(Benzylthio)-4-(4-methoxyphenoxy)thieno[3,2-d]pyrimidine (C20H16N2O2S2) is characterized by a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
