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 (Z)-3-(5-(4-hydroxy-3-methoxybenzylidene)-4-oxo-2-thioxothiazolidin-3-yl)benzoic acid.
CATO supplies (Z)-3-(5-(4-hydroxy-3-methoxybenzylidene)-4-oxo-2-thioxothiazolidin-3-yl)benzoic acid (CAS 5362-64-1), a certified reference material (molecular formula C18H13NO5S2, MW 387.43 g/mol) for analytical method development and quality control.
Structurally, (Z)-3-(5-(4-hydroxy-3-methoxybenzylidene)-4-oxo-2-thioxothiazolidin-3-yl)benzoic acid (C18H13NO5S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 387.43 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
