Chemical Structure
Description
Structurally, 3-(2-(3-Phenylureido)thiazol-4-yl)-N-(thiophen-2-ylmethyl)propanamide (C18H18N4O2S2) 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 386.49 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).
3-(2-(3-Phenylureido)thiazol-4-yl)-N-(thiophen-2-ylmethyl)propanamide (CAS 1040648-09-6) is a high-purity analytical reference standard with the molecular formula C18H18N4O2S2 and a molecular weight of 386.49 g/mol.
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.
