CAS 85-44-9
:Phthalic anhydride
Description:
Phthalic anhydride, with the CAS number 85-44-9, is a white crystalline solid that is primarily used in the production of plasticizers, resins, and dyes. It is an anhydride of phthalic acid and is characterized by its high reactivity, particularly with alcohols and amines, leading to the formation of esters and amides, respectively. Phthalic anhydride has a melting point around room temperature and is soluble in organic solvents such as benzene, toluene, and acetone, but is insoluble in water. It has a distinct, pungent odor and can be irritating to the skin, eyes, and respiratory system. The substance is produced through the oxidation of naphthalene or ortho-xylene and is a key intermediate in the synthesis of various chemical compounds. Due to its reactivity, it is important to handle phthalic anhydride with care, following appropriate safety protocols to minimize exposure and environmental impact.

CAS:<p>Phthalic anhydride is a chemical compound that is used as a catalyst in the production of sodium salts, such as sodium ethylate. It is also used to modify fatty acids, and is a component of many plastics. Phthalic anhydride is chemically stable and has been shown to have no adverse effects on antibody response or hydroxyl group levels. Phthalic anhydride also has high reactivity with glycol ethers, which can be used as an oxidation catalyst for reactions involving alcohols.</p>Formula:C8H4O3Purity:Min. 98 Area-%Color and Shape:PowderMolecular weight:148.12 g/molPhthalic Anhydride ACS, 99%
