(1S,4R)-4-fluorocyclopent-2-en-1-ol CAS 2165684-29-5

Description

Compared with other compounds in its class, the molecular weight of 102.11 g/mol gives (1S,4R)-4-fluorocyclopent-2-en-1-ol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(1S,4R)-4-fluorocyclopent-2-en-1-ol (CAS 2165684-29-5), molecular formula C5H7FO and molecular weight 102.11 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (1S,4R)-4-fluorocyclopent-2-en-1-ol (C5H7FO) contains a hydroxyl group, an ether linkage, fluorine 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 102.11 g/mol, it falls into the low-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.

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.
