Chemical Structure
Description
The occurrence of 2-(5-Methyl-2-thienyl)pyrrolidine Hydrochloride is closely related to a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-(5-Methyl-2-thienyl)pyrrolidine Hydrochloride (CAS 1256482-77-5) is a high-purity analytical reference standard with the molecular formula C9H13NSHCl and a molecular weight of 203.73 g/mol.
2-(5-Methyl-2-thienyl)pyrrolidine Hydrochloride (C9H13NSHCl) contains a nitrile group, sulfur-containing functionality, chlorine substitution. Halogen substitution raises its density and boiling point; 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.
