Description of DIAD
Diisopropyl azodicarboxylate (DIAD) is the diisopropyl ester of azodicarboxylic acid. It is used as a reagent in the production of many organic compounds. It is often used in the Mitsunobu reaction where it serves as an oxidizer of triphenylphosphine to triphenylphosphine oxide. It has also been used to generate aza-Baylis-Hillman adducts with acrylates. It can also serve as a selective deprotectant of N-benzyl groups in the presence of other protecting groups.
It is sometimes preferred to diethyl azodicarboxylate (DEAD) because it is more hindered, and thus less likely to form hydrazide byproducts.

What is DIAD?
With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is Diisopropyl azodicarboxylate which has developed particularly rapidly in recent years. Do you know about DIAD?
The official answer:Diisopropyl azodicarboxylate is a liquid foaming agent for vinyl resins with the molecular formula (CH3)2CHOOCN=NCOOCH(CH3)2. It is an orange-red transparent oily liquid and can be used to make light-coloured vinyl foams. It has a homogeneous microporous structure, and depending on the formulation and processing conditions, closed or open cell foam can be obtained. It is also used as a pharmaceutical intermediate and as a reagent in organic synthesis.
