tert-Butyl 3-hydroxy-3-(trifluoromethyl)azepane-1-carboxylate CAS 1823863-12-2

Description

Compared with other compounds in its class, the molecular weight of 283.29 g/mol gives tert-Butyl 3-hydroxy-3-(trifluoromethyl)azepane-1-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

tert-Butyl 3-hydroxy-3-(trifluoromethyl)azepane-1-carboxylate (CAS 1823863-12-2) is a high-purity analytical reference standard with the molecular formula C12H20F3NO3 and a molecular weight of 283.29 g/mol.

tert-Butyl 3-hydroxy-3-(trifluoromethyl)azepane-1-carboxylate (C12H20F3NO3) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
