Chemical Structure

3,4-diaminobenzonitrile CAS 17626-40-3 chemical structure

Description

3,4-diaminobenzonitrile (CAS 17626-40-3) is a high-purity analytical reference standard with the molecular formula C7H13N3 and a molecular weight of 139.20 g/mol.

The molecular framework of 3,4-diaminobenzonitrile (C7H13N3) is characterized by a nitrile group. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.

As a certified reference material (CRM), 3,4-diaminobenzonitrile 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.
