Chemical Structure
Description
N-((2,3-dihydrobenzofuran-5-yl)methyl)cyclopentanamine (CAS 1157544-58-5) is a high-purity analytical reference standard with the molecular formula C14H19NO and a molecular weight of 217.31 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, N-((2,3-dihydrobenzofuran-5-yl)methyl)cyclopentanamine is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 217.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
