Cyclopentyl-acetic acid chloromethyl ester (CAS 344326-08-5) is a high-purity analytical reference standard with the molecular formula C8H13ClO2 and a molecular weight of 176.64 g/mol.
Structurally, Cyclopentyl-acetic acid chloromethyl ester (C8H13ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 176.64 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
