Chemical Structure
Description
As a certified reference material (CRM), 3,3'-(Buta-1,3-diyne-1,4-diyl)dianiline 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'-(Buta-1,3-diyne-1,4-diyl)dianiline (CAS 31661-59-3) is a high-purity analytical reference standard with the molecular formula C16H12N2 and a molecular weight of 232.28 g/mol.
3,3'-(Buta-1,3-diyne-1,4-diyl)dianiline (C16H12N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
