Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,5-Dichloro-2-methoxy-4-(trifluoromethyl)benzene (CAS 1081849-77-5) is a high-purity analytical reference standard with the molecular formula C8H5Cl2F3O and a molecular weight of 245.03 g/mol.
Based on its molecular formula C8H5Cl2F3O, 1,5-Dichloro-2-methoxy-4-(trifluoromethyl)benzene contains a hydroxyl group, an ether linkage, fluorine/chlorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 245.03 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
