Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (E)-[(2-{[(4-chlorophenyl)methyl]sulfanyl}quinolin-3-yl)methylidene]amino thiophene-2-carboxylate.
(E)-[(2-{[(4-chlorophenyl)methyl]sulfanyl}quinolin-3-yl)methylidene]amino thiophene-2-carboxylate (CAS 478065-91-7), molecular formula C22H15ClN2O2S2 and molecular weight 438.95 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C22H15ClN2O2S2, (E)-[(2-{[(4-chlorophenyl)methyl]sulfanyl}quinolin-3-yl)methylidene]amino thiophene-2-carboxylate contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 438.95 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
