Product Description:

Oxima, chemically known as ethyl 2-(hydroxyimino)cyanoacetate, is a bifunctional organic compound featuring both a cyano group and an oxime (hydroxyimino) ester moiety. Its molecular structure allows it to serve as a versatile synthetic intermediate in organic chemistry. This compound is primarily utilized as a key building block in the pharmaceutical industry for the synthesis of heterocyclic compounds, particularly those with potential biological activities such as antimicrobial or anticancer agents. The oxime and cyano functionalities enable it to participate in cyclization reactions, forming pyrazoles, isoxazoles, and other nitrogen-containing heterocycles. Additionally, it is employed in the preparation of agrochemical intermediates and specialty fine chemicals. As a general synthetic building block, Oxima is also valued in research laboratories for constructing complex molecular architectures. Its reactivity under mild conditions makes it suitable for both academic and industrial process development. Safety precautions should be taken due to its potential irritant properties.
