The objective of this paper was to establish a HPLC method for determining benorilate tablets. A C18 column was used. The mobile phase consisted of methanol and water (56:44, adjusted to pH 3.5 with phosphoric acid). The UV detector was set at 240 nm. The calibration curve showed good linearity over the range of 0.52-6.24 μg (r = 0.9999), and the average recovery rate was 101.1%. The new method could be used to determine the content of benorilate in benorilate tablets. This study involved multiple reactions and reactants, such as 4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5Computed Properties of C17H15NO5).
4-Acetamidophenyl 2-acetoxybenzoate (cas: 5003-48-5) belongs to esters. Esters perform as high-grade solvents for a broad array of plastics, plasticizers, resins, and lacquers, and are one of the largest classes of synthetic lubricants on the commercial market. Many esters have the potential for conformational isomerism, but they tend to adopt an s-cis (or Z) conformation rather than the s-trans (or E) alternative, due to a combination of hyperconjugation and dipole minimization effects. The preference for the Z conformation is influenced by the nature of the substituents and solvent, if present. Lactones with small rings are restricted to the s-trans (i.e. E) conformation due to their cyclic structure.Computed Properties of C17H15NO5
