Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-(4-Oxo-5-(thiophen-2-ylmethylene)-2-thioxothiazolidin-3-yl)-N-(m-tolyl)propanamide.
CATO supplies 3-(4-Oxo-5-(thiophen-2-ylmethylene)-2-thioxothiazolidin-3-yl)-N-(m-tolyl)propanamide (CAS 308292-24-2), a certified reference material (molecular formula C18H16N2O2S3, MW 388.53 g/mol) for analytical method development and quality control.
Structurally, 3-(4-Oxo-5-(thiophen-2-ylmethylene)-2-thioxothiazolidin-3-yl)-N-(m-tolyl)propanamide (C18H16N2O2S3) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 388.53 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
