Chemical Structure

1,3-Diisocyanobenzene CAS 935-27-3 chemical structure

Description

As a certified reference material (CRM), 1,3-Diisocyanobenzene 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.

1,3-Diisocyanobenzene (CAS 935-27-3) is a high-purity analytical reference standard with the molecular formula C8H4N2 and a molecular weight of 128.13 g/mol.

The molecular framework of 1,3-Diisocyanobenzene (C8H4N2) is characterized by a nitrogen-containing heterocyclic scaffold, 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
