Chemical Structure

4-Methylpyridine-2,6-dicarbonitrile CAS 21635-92-7 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4-Methylpyridine-2,6-dicarbonitrile is typically pale yellow to yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 143.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

4-Methylpyridine-2,6-dicarbonitrile (CAS 21635-92-7), molecular formula C8H5N3 and molecular weight 143.15 g/mol, is a CATO reference standard with documented purity and traceability.

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), 4-Methylpyridine-2,6-dicarbonitrile 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.
