Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-(3-Phenylureido)-N-((tetrahydrofuran-2-yl)methyl)thiazole-4-carboxamide (CAS 941926-87-0), molecular formula C16H18N4O3S and molecular weight 346.40 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 2-(3-Phenylureido)-N-((tetrahydrofuran-2-yl)methyl)thiazole-4-carboxamide (C16H18N4O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 10.0, corresponding to approximately 10 ring(s) or double-bond equivalent(s). With a molecular weight of 346.40 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).
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.
