Chemical Structure
Description
(S)-methyl 2-(cyclopentanecarboxamido)pent-4-enoate (CAS 2007916-33-6), molecular formula C12H19NO3 and molecular weight 225.28 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H19NO3, (S)-methyl 2-(cyclopentanecarboxamido)pent-4-enoate 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 225.28 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
