Chemical Structure

1,4-Di(pyridin-3-yl)buta-1,3-diyne CAS 5069-24-9 chemical structure

Description

As a certified reference material (CRM), 1,4-Di(pyridin-3-yl)buta-1,3-diyne 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.

1,4-Di(pyridin-3-yl)buta-1,3-diyne (CAS 5069-24-9), molecular formula C14H8N2 and molecular weight 204.23 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 1,4-Di(pyridin-3-yl)buta-1,3-diyne is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 204.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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