Chemical Structure
Description
1-{thieno[3,2-b]thiophen-2-yl}methanamine hydrochloride (CAS 1172699-35-2), molecular formula C7H7NS2HCl and molecular weight 205.72 g/mol, is a CATO reference standard with documented purity and traceability.
1-{thieno[3,2-b]thiophen-2-yl}methanamine hydrochloride (C7H7NS2HCl) contains a nitrile group, sulfur-containing functionality, chlorine substitution, an aromatic ring system. 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.
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.
CATO manufactures 1-{thieno[3,2-b]thiophen-2-yl}methanamine 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.
