Chemical Structure
Description
The occurrence of (5-Chloro-1H-benzo[d]imidazol-2-yl)methanethiol is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(5-Chloro-1H-benzo[d]imidazol-2-yl)methanethiol (CAS 68946-04-3), molecular formula C8H7ClN2S and molecular weight 198.67 g/mol, is a CATO reference standard with documented purity and traceability.
(5-Chloro-1H-benzo[d]imidazol-2-yl)methanethiol (C8H7ClN2S) contains a nitrogen-containing heterocyclic scaffold, 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. 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.
As a certified reference material (CRM), (5-Chloro-1H-benzo[d]imidazol-2-yl)methanethiol meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
