Chemical Structure

4-amino-2,5-difluorobenzenethiol CAS 782413-10-9 chemical structure

Description

4-amino-2,5-difluorobenzenethiol (CAS 782413-10-9) is a high-purity analytical reference standard with the molecular formula C6H5F2NS and a molecular weight of 161.17 g/mol.

4-amino-2,5-difluorobenzenethiol (C6H5F2NS) contains a nitrile group, sulfur-containing functionality, fluorine 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 4-amino-2,5-difluorobenzenethiol 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.
