Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
3-Chloro-N-(2-fluoro-4-methylphenyl)benzamide (CAS 1037953-69-7) is a high-purity analytical reference standard with the molecular formula C14H11ClFNO and a molecular weight of 263.69 g/mol.
Based on its molecular formula C14H11ClFNO, 3-Chloro-N-(2-fluoro-4-methylphenyl)benzamide contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 263.69 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
