4,5,6,7-tetrafluoro-2-({[3-(trifluoromethyl)phenyl]thio}methyl)benzo[b]furan CAS 256525-96-9

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,5,6,7-tetrafluoro-2-({[3-(trifluoromethyl)phenyl]thio}methyl)benzo[b]furan.

4,5,6,7-tetrafluoro-2-({[3-(trifluoromethyl)phenyl]thio}methyl)benzo[b]furan (CAS 256525-96-9) is a high-purity analytical reference standard with the molecular formula C16H7F7OS and a molecular weight of 380.28 g/mol.

Owing to sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution, a polycyclic aromatic system, 4,5,6,7-tetrafluoro-2-({[3-(trifluoromethyl)phenyl]thio}methyl)benzo[b]furan is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 380.28 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.
