Chemistry can be defined as the study of matter and the changes it undergoes. You¡¯ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology. 101-55-3, Name is 1-Bromo-4-phenoxybenzene, molecular formula is , belongs to ethers-buliding-blocks compound.

A Liquid Chromatographic Analysis of Gemifloxacin in Pharmaceutical Preparations Using 4-bromomethyl-7-methoxycoumarin Reagent
Objective: In this study, analysis of gemifloxacin in pharmaceutical preparations was performed in the presence of 4-bromomethyl-7-methoxycoumarin reagent and dibenzo-18-crown-6 ether catalyst, by high-performance liquid chromatography. Methods: The excitation wavelength of the compound formed as a result of the derivatization process was found as lambda ext. =325 nm and the emission wavelength as lambda em=390 nm. Optimum reaction conditions were carefully studied. Chromatographic sepal ado us were performed in a 150 cm x4.6 mm, 5 mu m I.D C18 column, and the mobile phase consisting of acetonitrile: 0.05 M aqueous ammonium acetate (pH=5.0) (70:30, v/v) under flow rate of 1.0 mL/min. Results: The calibration curve was found to be linear in the range of 10-200 ng.mL(-1) Average recovery was 100.32% and relative standard deviation values were below 2%. Conclusion: The method developed has been successfully applied in the analysis of the drug substance in pharmaceutical preparations.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 101-55-3, in my other articles.
