Chemical Structure

2-Ethynyl-1H-pyrrole CAS 67237-51-8 chemical structure

Description

Structurally, 2-Ethynyl-1H-pyrrole (C6H5N) contains a nitrile group, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 91.11 g/mol, it falls into the low-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

CATO supplies 2-Ethynyl-1H-pyrrole (CAS 67237-51-8), a certified reference material (molecular formula C6H5N, MW 91.11 g/mol) for analytical method development and quality control.

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.
