Chemical Structure

2,5-Diethynylaniline CAS 137000-70-5 chemical structure

Description

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 2,5-Diethynylaniline is typically pale yellow to yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 141.17 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.

2,5-Diethynylaniline (CAS 137000-70-5) is a high-purity analytical reference standard with the molecular formula C10H7N and a molecular weight of 141.17 g/mol.

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

CATO manufactures 2,5-Diethynylaniline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
