Abstract: An electronic device includes a first body and a second body. The first body has a lock portion. The second body includes a main body, a lock component, an actuator and a retainer. The main body is configured to be detachably assembled to the first body. The lock component is movably disposed in the main body. The actuator is disposed in the main body. The retainer is connected to the actuator, in which when the main body is detachably assembled to the first body and the lock component is located at a first position, the lock component locks the lock portion to prevent the main body being separated from the first body, and the actuator is configured to drive the retainer pushing the lock component so as to prevent the lock component departing from the first position.

Abstract: An electronic device including a first body, a driving component, and a connector module is provided. The first body includes a main portion and an edge portion, wherein the thickness of the edge portion is smaller than the thickness of the main portion, and the edge portion has an opening. The driving component and the connector module are slidably disposed in the first body and so that the driving component drives the connector module to move from the main portion to the edge portion and the connector module is exposed from the opening of the edge portion.

Abstract: The present invention is related to a precursor for no-carrier-added fluorine-18 labeled ethacrynic acid, N-(4-[18F]fluorobutyl)-Ethacrynic amide([18F]FBuEA) and the preparation method for HPLC non-radioactive standards. Its chemical structure is shown in the following: In the precursor, R1 represents a protective group for the amide functional group; R2 represents leaving group; or R1 represents carboxyl group, R2 represents p-tosyloxy, methane sulfonyloxy group or trifluoromethane sulfonyloxy group or bromine (Br). For the HPLC non-radioactive standards, R1 represents a protective group for the amide functional group and hydrogen, R2 represents fluorine.
