2-[2-Nitro-4-(trifluoromethyl)phenyl]acetic Acid CAS 1735-91-7 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[2-Nitro-4-(trifluoromethyl)phenyl]acetic Acid.

2-[2-Nitro-4-(trifluoromethyl)phenyl]acetic Acid (CAS 1735-91-7) is a high-purity analytical reference standard with the molecular formula C9H6F3NO4 and a molecular weight of 249.14 g/mol.

Based on its molecular formula C9H6F3NO4, 2-[2-Nitro-4-(trifluoromethyl)phenyl]acetic Acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 249.14 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.
