Chemical Structure
Description
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.
1-Allyl-4-methyl-1H-pyrrole-2-carboxylic acid (CAS 397329-68-9) is a high-purity analytical reference standard with the molecular formula C9H11NO2 and a molecular weight of 165.19 g/mol.
Based on its molecular formula C9H11NO2, 1-Allyl-4-methyl-1H-pyrrole-2-carboxylic acid contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 165.19 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.
