Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
((1R,3r)-3-fluorocyclobutyl)hydrazine (CAS 2167001-03-6), molecular formula C4H9FN2 and molecular weight 104.13 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to fluorine substitution, ((1R,3r)-3-fluorocyclobutyl)hydrazine is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 104.13 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.
