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 1-[Chloro(difluoro)methoxy]-3-fluoro-5-(trifluoromethyl)benzene (CAS 1417567-13-5), a certified reference material (molecular formula C8H3ClF6O, MW 264.55 g/mol) for analytical method development and quality control.
Structurally, 1-[Chloro(difluoro)methoxy]-3-fluoro-5-(trifluoromethyl)benzene (C8H3ClF6O) contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 264.55 g/mol, it falls into the medium-molecular-weight range. 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.
