Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

1-(4-Methyl-1H-pyrrol-3-yl)ethanone (CAS 18818-30-9) is a high-purity analytical reference standard with the molecular formula C7H9NO and a molecular weight of 123.15 g/mol.

Based on its molecular formula C7H9NO, 1-(4-Methyl-1H-pyrrol-3-yl)ethanone contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 123.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
