Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3,5-Difluoro-4-methoxyphenyl)acetonitrile.
2-(3,5-Difluoro-4-methoxyphenyl)acetonitrile (CAS 886498-79-9), molecular formula C9H7F2NO and molecular weight 183.15 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, 2-(3,5-Difluoro-4-methoxyphenyl)acetonitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 183.15 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.
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.
