Chemical Structure

3,3-Diethylpent-1-yne CAS 919-23-3 chemical structure

Description

3,3-Diethylpent-1-yne (CAS 919-23-3), molecular formula C9H16 and molecular weight 124.22 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C9H16, 3,3-Diethylpent-1-yne contains an organic framework; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 124.22 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
