Chemical Structure

N-(4-Fluoro-5-methyl-2-nitrophenyl)acetamide CAS 97398-89-5 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 N-(4-Fluoro-5-methyl-2-nitrophenyl)acetamide.

N-(4-Fluoro-5-methyl-2-nitrophenyl)acetamide (CAS 97398-89-5) is a high-purity analytical reference standard with the molecular formula C9H9FN2O3 and a molecular weight of 212.18 g/mol.

The molecular framework of N-(4-Fluoro-5-methyl-2-nitrophenyl)acetamide (C9H9FN2O3) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
