Chemical Structure

3-Ethyl-1-methyl-1H-pyrrole CAS 53871-25-3 chemical structure

Description

The occurrence of 3-Ethyl-1-methyl-1H-pyrrole is closely related to a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Ethyl-1-methyl-1H-pyrrole (CAS 53871-25-3), molecular formula C7H11N and molecular weight 109.17 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 3-Ethyl-1-methyl-1H-pyrrole (C7H11N) contains a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 109.17 g/mol, it falls into the low-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
