Tetrahydrophthalic Anhydride 85-43-8 Usage
Tetrahydrophthalic Anhydride (THPA), in the form of a white crystalline powder, is created from the reaction of butadiene with maleic anhydride. Highly toxic and a strong irritant to skin, eyes and mucous membranes. Corrosive to skin and metal. Tetrahydrophthalic anhydride (THPA) as curing agents were studied using dynamic differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and dynamic mechanical analysis (DMA). 1,2,3,6-Tetrahydrophthalic anhydride (THPA) can be used as: A curing agent for epoxides. A chemical modifier in the modification of polystyrene.

New Cyclic Imides and Quinazolin-2,4-diones Based on 1,2,3,6-Tetrahydrophthalic anhydride: Synthesis, Semiempirical Study and in vitro Evaluation
Ahmed M. Abo-Bakr, Mohamed Mobarak Taha, Antonous M. Mekhael, Mounir A. Mohamed
Page/Page column 4-6, (2018/10/11)
1,2,3,6-Tetrahydrophthalic anhydride (1) was used as a precursor for the synthesis of new cyclic imides by reacting with several reagents such as 2-aminothiazole, 4-aminopyridine, 2-aminobenzothiazole, cyanoacetic acid hydrazide, amino guanidine, 2,2-diaminomalononitrile, hexamethylenediamine or 2-(amino-ethyldisulfanyl)-ethylamine where the corresponding cyclic imides 2-9 were obtained respectively. The in vitro study of some selected imides and quinazolin-2,4-dinoes against two strains of bacteria possesses a high inhibition effect.
Formation of new substituted (1,3)oxazepine 1,5-diones via reaction of Exo-3,6-epoxy-1,2,3,6-tetrahydrophthalic Anhydride with Schiff’s bases

AIP Conference Proceedings 2457, 030005 (2023)
These Schiff's bases were treated in anhydrous 1,4-dioxane with Exo-3,6-epoxy-1,2,3,6-tetrahydrophthalic Anhydride under reflux in circumstances that gave substituted 1,3-oxazepine-1,5-dione. The products were isolated, purified and characterized by their melting points , FT-IR and 1HNMR spectra, which are found to be 1,3oxazepine 1,5-diones derivatives.
