3-hydroxycyclobutanecarbonitrile (CAS 20249-17-6) is a high-purity analytical reference standard with the molecular formula C5H7NO and a molecular weight of 97.12 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, 3-hydroxycyclobutanecarbonitrile is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 97.12 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
