Chemical Structure
Description
3-(Thiophen-2-yl)-N-(1h-1,2,4-triazol-5-yl)propanamide (CAS 1050813-59-6), molecular formula C9H10N4OS and molecular weight 222.27 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(Thiophen-2-yl)-N-(1h-1,2,4-triazol-5-yl)propanamide (C9H10N4OS) contains a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 7.0, corresponding to approximately 7 ring(s) or double-bond equivalent(s). With a molecular weight of 222.27 g/mol, it falls into the medium-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.
