Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 179.64 g/mol gives 2-Amino-5-fluorobenzenethiol hydrochloride distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Amino-5-fluorobenzenethiol hydrochloride (CAS 245117-22-0) is a high-purity analytical reference standard with the molecular formula C6H6FNSHCl and a molecular weight of 179.64 g/mol.
Based on its molecular formula C6H6FNSHCl, 2-Amino-5-fluorobenzenethiol hydrochloride contains a nitrile group, sulfur-containing functionality, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 179.64 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
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 2-Amino-5-fluorobenzenethiol 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.
