Descripción

General description

Perchloric acid (HClO₄), an oxygen acid of chlorine, is a colorless liquid. It is strongly acidic in nature. Hydrates of perchloric acid are obtained on its dissolution in water.

Application

• Development of the Chromatographic Method for Simultaneous Determination of Azaperone and Azaperol in Animal Kidneys and Livers.: This study used perchloric acid for the sample preparation in HPLC analysis, which is crucial for veterinary drug residue analysis in food safety research (Koska and Kubalczyk, 2022).


• Development of a High Performance Liquid Chromatography with Diode Array Detector (HPLC-DAD) Method for Determination of Biogenic Amines in Ripened Cheeses.: The research utilized perchloric acid for sample deproteinization, demonstrating its application in food chemistry for the quality control of dairy products (Pawul-Gruba et al., 2022).


• Vibrational and impedance analysis of the beta-stannic acid samples plasticized by perchloric acid.: This study employed perchloric acid in the plasticization process, essential for materials science research on improving the properties of beta-stannic acid (Karelin et al., 2022).


• Measurement of tigecycline in dried blood spots by LC-MS/MS and comparison tigecycline concentrations between whole blood and plasma.: Perchloric acid was used in the sample preparation for LC-MS/MS analysis, crucial for pharmacokinetic studies in clinical research (Yan et al., 2023).


• SiO(2)-supported HClO(4) catalyzed synthesis of (Z)-thiazolylhydrazonoindolin-2-ones and their electrochemical properties.: The research highlights the use of perchloric acid as a catalyst, demonstrating its application in organic synthesis and electrochemistry (Shaik et al., 2022).
