Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-chloro-1,7-dimethyl-1H-1,3-benzodiazole (CAS 24133-82-2), molecular formula C9H9ClN2 and molecular weight 180.63 g/mol, is a CATO reference standard with documented purity and traceability.
2-chloro-1,7-dimethyl-1H-1,3-benzodiazole (C9H9ClN2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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.
As a certified reference material (CRM), 2-chloro-1,7-dimethyl-1H-1,3-benzodiazole 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.
