1-phenyl-, 2-oxime-1,2-Propanedione - Introduction

1-Phenyl-1,2-propanedione-2-oxime (abbreviated as PBD) is an organic compound with the chemical formula C9H9NO3.

In terms of properties, PBD is a white solid with an organic ketone with a phenyl group and an oxime group substituted structure. It has good solubility, can be dissolved in organic solvents, and is relatively stable. It can form complexes with some metals and has certain optical activity.

In terms of application, PBD is widely used as a reagent in organic synthesis. It can react with ketones, anhydrides and α-keto acids to generate products with oxamide or oxime substitution. These products can play an important role in biochemistry, Pharmaceutical Research and organic synthesis.

There are two main methods of preparing PBD. One is the formation of PBD by the reaction of 1-phenyl -1, 2-propanedione and hydroxylamine, and the reaction conditions are carried out under basic conditions. Another method is prepared by reacting p -1-phenyl -1, 2-propanedione with nitrous acid.

Regarding the safety information of PBD, it is an organic compound and needs to be operated safely. During use and storage, contact with skin and eyes should be avoided to avoid irritation and damage. Appropriate laboratory equipment and personal protective equipment, such as gloves, goggles, etc., are required for laboratory operations. In addition, PBD should also be used in a well-ventilated area to avoid inhaling excessive amounts of gas. If inhaled or ingested, seek medical attention immediately.
