Chemical Structure
Description
The occurrence of 3-Ethyl-2-iodo-4-methyl-1H-pyrrole is closely related to a nitrile group, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-Ethyl-2-iodo-4-methyl-1H-pyrrole (CAS 192887-91-5) is a high-purity analytical reference standard with the molecular formula C7H10IN and a molecular weight of 235.07 g/mol.
Structurally, 3-Ethyl-2-iodo-4-methyl-1H-pyrrole (C7H10IN) contains a nitrile group, iodine substitution. 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 235.07 g/mol, it falls into the medium-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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
