Chemical Structure
Description
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.
2,2-Difluorocyclohexanecarbonitrile (CAS 1554428-52-2), molecular formula C7H9F2N and molecular weight 145.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, fluorine substitution, 2,2-Difluorocyclohexanecarbonitrile is typically white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 145.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
