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.
CATO supplies (2,6-Difluoro-4-methylphenyl)methanol (CAS 252004-32-3), a certified reference material (molecular formula C8H8F2O, MW 158.15 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, (2,6-Difluoro-4-methylphenyl)methanol is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 158.15 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.
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.
