Chemical Structure
Description
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.
N'-[(1E)-[2,5-Dimethyl-1-(pyrazin-2-yl)-1H-pyrrol-3-yl]methylidene]thiophene-2-carbohydrazide (CAS 866009-60-1), molecular formula C16H15N5OS and molecular weight 325.39 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, N'-[(1E)-[2,5-Dimethyl-1-(pyrazin-2-yl)-1H-pyrrol-3-yl]methylidene]thiophene-2-carbohydrazide (C16H15N5OS) 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 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 325.39 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.
