Chemical Structure
Description
CATO supplies 5-(3-Fluorocyclobutyl)-1H-pyrazol-3-amine (CAS 2228036-45-9), a certified reference material (molecular formula C7H10FN3, MW 155.17 g/mol) for analytical method development and quality control.
Owing to a nitrile group, fluorine substitution, an aromatic ring system, 5-(3-Fluorocyclobutyl)-1H-pyrazol-3-amine is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 155.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
