Chemical Structure

Methyl 4-(difluoromethoxy)-3-nitrobenzoate CAS 1154278-25-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 247.15 g/mol gives Methyl 4-(difluoromethoxy)-3-nitrobenzoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Methyl 4-(difluoromethoxy)-3-nitrobenzoate (CAS 1154278-25-7) is a high-purity analytical reference standard with the molecular formula C9H7F2NO5 and a molecular weight of 247.15 g/mol.

Based on its molecular formula C9H7F2NO5, Methyl 4-(difluoromethoxy)-3-nitrobenzoate 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 247.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
