Methyl oxalyl chloride

Description:

Methyl oxalyl chloride, with the CAS number 5781-53-3, is an organic compound characterized by its structure, which includes a methyl group and two oxalyl chloride functional groups. It is a colorless to pale yellow liquid that is known for its strong reactivity, particularly as a chlorinating agent. This compound has a pungent odor and is highly corrosive, necessitating careful handling and storage in a well-ventilated area with appropriate personal protective equipment. Methyl oxalyl chloride is soluble in organic solvents but reacts vigorously with water, releasing hydrochloric acid and forming methyl oxalate. It is primarily used in organic synthesis, particularly in the preparation of various chemical intermediates and in the production of pharmaceuticals and agrochemicals. Due to its reactivity, it poses significant health hazards, including respiratory irritation and potential skin burns, making it essential to follow safety protocols when working with this substance.

Methyl chlorooxoacetate

CAS: 5781-53-3

Methyl chlorooxoacetate is an oxalyl ester that has been used for the synthesis of glycol esters. Methyl chlorooxoacetate has been shown to have a high solubility in water and organic solvents, which is desirable for industrial processes. This molecule also has the ability to be acylated with various organic groups and can act as a process-optimization agent in plant physiology. Methyl chlorooxoacetate binds as a receptor to growth factors and HIV infection, which leads to amide formation and carbonyl group formation.
