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 ).
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.
Other Notes:	Reagent for the decomposition of metals and organic compounds (danger of explosions)
