CAS 703-59-3
:Homophthalic anhydride
Description:
Homophthalic anhydride, with the CAS number 703-59-3, is an organic compound characterized by its anhydride functional group derived from homophthalic acid. It appears as a white to light yellow crystalline solid and is known for its high melting point and low solubility in water, but it is soluble in organic solvents such as acetone and ethyl acetate. This compound is primarily used in the synthesis of various polymers, particularly in the production of epoxy resins and as a hardener in coatings and adhesives. Homophthalic anhydride exhibits reactivity typical of anhydrides, readily undergoing hydrolysis to form homophthalic acid in the presence of water. It is also known for its potential applications in the manufacture of dyes and pharmaceuticals. Safety considerations include handling it with care, as it can be irritating to the skin, eyes, and respiratory system. Proper safety measures, including the use of personal protective equipment, are recommended when working with this chemical.

CAS:<p>The o-carboxyphenylacetic acid cyclic anhydride (OCPA) is a compound that has been shown to have antimicrobial activity. It inhibits the growth of bacteria by binding to the receptor site of bacterial enzymes and blocking the synthesis of fungal cell walls. OCPA can also be used in the treatment of inflammatory diseases, such as cancer and arthritis. The mode of action for OCPA is not well understood but it is believed that it may interfere with amine metabolism or act as a hydrogen bond acceptor. Analysis of OCPA has been done using analytical methods such as gas chromatography mass spectrometry (GCMS), nuclear magnetic resonance (NMR), and infrared spectroscopy (IR).</p>Formula:C9H6O3Purity:Min. 95%Color and Shape:PowderMolecular weight:162.14 g/mol
