Related Product Features:

Diisopropyl azodicarboxylate (DIAD) is an orange crystal or liquid with a high assay of ≥99.0%.
It has a density of 1.02 and a boiling point of 75℃ at 0.2 mmHg.
DIAD is insoluble in water and stable at room temperature under normal conditions.
Used as an oxidizer in the Mitsunobu reaction and for generating aza-Baylis-Hillman adducts.
Preferred over diethyl azodicarboxylate (DEAD) due to reduced hydrazide byproduct formation.
Stored at 2-8℃ and classified under Hazard Class 9 with specific safety statements.
Features a flash point of 106℃ and a refractive index of 1.418-1.422.
Applicable in selective deprotection of N-benzyl groups in organic synthesis.

Las preguntas:

What is Diisopropyl Azodicarboxylate (DIAD) used for?

DIAD is used as a reagent in organic synthesis, particularly in the Mitsunobu reaction and for generating aza-Baylis-Hillman adducts. It also serves as a selective deprotectant of N-benzyl groups.
What are the storage conditions for DIAD?

DIAD should be stored at 2-8℃ in closed containers under normal storage and handling conditions to maintain stability.
Why is DIAD preferred over DEAD in some reactions?

DIAD is more hindered than DEAD, which reduces the likelihood of forming hydrazide byproducts, making it a preferred choice in certain synthetic applications.
