N,N-Diethyl-4-ethynylaniline CAS 41876-70-4

Description

Compared with other compounds in its class, the molecular weight of 173.25 g/mol gives N,N-Diethyl-4-ethynylaniline distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

N,N-Diethyl-4-ethynylaniline (CAS 41876-70-4) is a high-purity analytical reference standard with the molecular formula C12H15N and a molecular weight of 173.25 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, N,N-Diethyl-4-ethynylaniline is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 173.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.

CATO manufactures N,N-Diethyl-4-ethynylaniline 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.
