2,2'-(Buta-1,3-diyne-1,4-diyl)dianiline CAS 31661-58-2

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2,2'-(Buta-1,3-diyne-1,4-diyl)dianiline.

2,2'-(Buta-1,3-diyne-1,4-diyl)dianiline (CAS 31661-58-2), molecular formula C16H12N2 and molecular weight 232.28 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C16H12N2, 2,2'-(Buta-1,3-diyne-1,4-diyl)dianiline contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 232.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), 2,2'-(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.
