Chemical Structure
Description
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
4,5,6,7-Tetrahydrothieno[2,3-c]pyridine Hydrochloride (CAS 28783-38-2) is a high-purity analytical reference standard with the molecular formula C7H9NSHCl and a molecular weight of 175.67 g/mol.
4,5,6,7-Tetrahydrothieno[2,3-c]pyridine Hydrochloride (C7H9NSHCl) 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO manufactures 4,5,6,7-Tetrahydrothieno[2,3-c]pyridine Hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
