Description
As a certified reference material (CRM), 3,3'-Dichlorobenzidine-d6 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.
3,3'-Dichlorobenzidine-d6 (CAS 93951-91-8), molecular formula C12H4D6Cl2N2 and molecular weight 259.16 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution, 3,3'-Dichlorobenzidine-d6 is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 259.16 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
