Chemical Structure
Description
2-(5-Fluoro-1H-benzo[d]imidazol-2-yl)ethanethiol (CAS 109949-20-4) is a high-purity analytical reference standard with the molecular formula C9H9FN2S and a molecular weight of 196.24 g/mol.
2-(5-Fluoro-1H-benzo[d]imidazol-2-yl)ethanethiol (C9H9FN2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, fluorine 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.
CATO manufactures 2-(5-Fluoro-1H-benzo[d]imidazol-2-yl)ethanethiol 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.
