Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
4,4'-(1H-Benzo[d]imidazole-4,7-diyl)dianiline (CAS 1998160-90-9) is a high-purity analytical reference standard with the molecular formula C19H16N4 and a molecular weight of 300.36 g/mol.
4,4'-(1H-Benzo[d]imidazole-4,7-diyl)dianiline (C19H16N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures 4,4'-(1H-Benzo[d]imidazole-4,7-diyl)dianiline 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.
