Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-{5-[2-(Benzyloxy)phenyl]-2-thienyl}ethanone.
1-{5-[2-(Benzyloxy)phenyl]-2-thienyl}ethanone (CAS 893741-47-4) is a high-purity analytical reference standard with the molecular formula C19H16O2S and a molecular weight of 308.39 g/mol.
1-{5-[2-(Benzyloxy)phenyl]-2-thienyl}ethanone (C19H16O2S) contains a steroid core, a sulfone group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; 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.
