3-Phenethyl-5-(pyridin-3-ylmethylene)-2-thioxothiazolidin-4-one CAS 670269-73-5

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Phenethyl-5-(pyridin-3-ylmethylene)-2-thioxothiazolidin-4-one.

3-Phenethyl-5-(pyridin-3-ylmethylene)-2-thioxothiazolidin-4-one (CAS 670269-73-5), molecular formula C17H14N2OS2 and molecular weight 326.44 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C17H14N2OS2, 3-Phenethyl-5-(pyridin-3-ylmethylene)-2-thioxothiazolidin-4-one contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 326.44 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.
