Chemical Structure
Description
(2,2-Difluoro-3-methylcyclopropyl)methanol (CAS 509072-72-4), molecular formula C5H8F2O and molecular weight 122.11 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2,2-Difluoro-3-methylcyclopropyl)methanol (C5H8F2O) contains a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 122.11 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.
