Chemical Structure
Description
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.
Tert-butyl (1-(3-fluoropropyl)azetidin-3-yl)carbamate (CAS 2222845-47-6), molecular formula C11H21FN2O2 and molecular weight 232.30 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, Tert-butyl (1-(3-fluoropropyl)azetidin-3-yl)carbamate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.30 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
