Chemical Structure
Description
4-Nitro-3-(trifluoromethyl)phenol (CAS 88-30-2) is a high-purity analytical reference standard with the molecular formula C7H4F3NO3 and a molecular weight of 207.11 g/mol.
Based on its molecular formula C7H4F3NO3, 4-Nitro-3-(trifluoromethyl)phenol contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 207.11 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.
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.
