Chemical Structure
Description
6-Chloro-2-(2-chlorophenyl)-1H-1,3-benzodiazol-1-ol (CAS 338978-74-8), molecular formula C13H8Cl2N2O and molecular weight 279.12 g/mol, is a CATO reference standard with documented purity and traceability.
6-Chloro-2-(2-chlorophenyl)-1H-1,3-benzodiazol-1-ol (C13H8Cl2N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
As a certified reference material (CRM), 6-Chloro-2-(2-chlorophenyl)-1H-1,3-benzodiazol-1-ol 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.
