Chemical Structure
Description
The occurrence of tert-Butyl 4,4-difluoro-5-hydroxypentanoate is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
tert-Butyl 4,4-difluoro-5-hydroxypentanoate (CAS 1782101-24-9), molecular formula C9H16F2O3 and molecular weight 210.22 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, tert-Butyl 4,4-difluoro-5-hydroxypentanoate (C9H16F2O3) contains a carboxylic acid group, 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 210.22 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
