3-Hydroxyphthalic anhydride Chemical Properties,Uses,Production
Description
3-Hydroxyphthalic anhydride: a valuable raw material for chemical industry and pharmaceutical research.
Phthalic anhydride derivatives have been applied as plasticizers and heat-resistant polymers in the chemical industry. One of its derivatives is the 3-hydroxyphthalic anhydride (3-HPA), which exhibits a hydroxyl group substituent in position 3. 3-Hydroxyphthalic anhydride can be used as raw material for heat-resistant resins such as epoxy resins, polyesters, polyimides, etc., or as raw material for physiologically active substances such as medicines and pesticides. It has been shown that 3-HPA can serve as a raw material to obtain drugs with potential applications, such as anticancer, antimicrobial and in treating diabetes, herpes, and HIV[1].

Beige powder
Uses
3-Hydroxyphthalic Anhydride is used to synthesize 3-Hydroxyphthalic Anhydride-modified human serum albumin whichhas high potency as a microbicide for prevention of the sexual transmission of HIV. It is also used as a reagent in organicsynthesis of other compounds including that of inhibitors of NF-κB derived from thalidomide.

Synthesis
In the presence of triethylamine, the 2-oxo-2, 5-dihydrofuran, and pivaloyl chloride reactions generate 2-valeryl oxo furans. The affixture with 2-valeryl oxo furans and maleic anhydride uses vitriolization, which thereby generates the method of 3-hydroxyl phthalic anhydride.
