Chemical Structure
Description
2-Methyl-3-pentyl-1H-pyrrole (CAS 18320-91-7) is a high-purity analytical reference standard with the molecular formula C10H17N and a molecular weight of 151.25 g/mol.
2-Methyl-3-pentyl-1H-pyrrole (C10H17N) contains a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
