Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[(3-Ethyl-4-oxo-2-thioxo-1,3-thiazolan-5-yliden)methyl]benzenecarboxylic acid.
4-[(3-Ethyl-4-oxo-2-thioxo-1,3-thiazolan-5-yliden)methyl]benzenecarboxylic acid (CAS 1474053-20-7) is a high-purity analytical reference standard with the molecular formula C13H11NO3S2 and a molecular weight of 293.36 g/mol.
Based on its molecular formula C13H11NO3S2, 4-[(3-Ethyl-4-oxo-2-thioxo-1,3-thiazolan-5-yliden)methyl]benzenecarboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 293.36 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.
