Chemical Structure
Description
As a certified reference material (CRM), 6-Chloro-1-[(2-chlorophenyl)methoxy]-2-phenyl-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.
6-Chloro-1-[(2-chlorophenyl)methoxy]-2-phenyl-1H-1,3-benzodiazole (CAS 338978-63-5) is a high-purity analytical reference standard with the molecular formula C20H14Cl2N2O and a molecular weight of 369.24 g/mol.
The molecular framework of 6-Chloro-1-[(2-chlorophenyl)methoxy]-2-phenyl-1H-1,3-benzodiazole (C20H14Cl2N2O) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
