Chemical Structure
Description
The occurrence of 4,5,6,7-Tetrahydrobenzothiophene-3-methanamine 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.
4,5,6,7-Tetrahydrobenzothiophene-3-methanamine (CAS 924838-30-2), molecular formula C9H13NSHCl and molecular weight 203.73 g/mol, is a CATO reference standard with documented purity and traceability.
4,5,6,7-Tetrahydrobenzothiophene-3-methanamine (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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
