Chemical Structure
Description
The occurrence of 4-ethyl-4,5,6,7-tetrahydrothieno[3,2-c]pyridine is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-ethyl-4,5,6,7-tetrahydrothieno[3,2-c]pyridine (CAS 900641-10-3), a certified reference material (molecular formula C9H13NS, MW 167.27 g/mol) for analytical method development and quality control.
4-ethyl-4,5,6,7-tetrahydrothieno[3,2-c]pyridine (C9H13NS) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
