VALERIC ANHYDRIDE Usage And Synthesis

Description

Valeric anhydride is an important organic synthetic raw material or intermediate component, often used in industrial or medical fields. It can be used in the preparation of butylphthalide, resin components, lutein esters, analgesics and organic glass.

Chemical Properties

clear colorless to yellow liquid

Uses

Valeric Anhydride is used in the synthesis of non-imadazole histamine H3-antagonists. Also used in the preparation of millepachine derivatives as a new class of tubulin polymerization inhibitors.

Uses

Valeric anhydride can be used as a reactant to synthesize:

• Alkyl 9-nitrocamptothecin esters by the esterification reaction.
• Modified bismuth metal-organic frameworks (Bi-MOFs).
• O-acylated chitosan nanofibers (CSNFs) for potential usage in biomaterials and food packaging.

Flammability and Explosibility

Non flammable
