Phthalic anhydride, 99%, Thermo Scientific™
Description
Phthalic anhydride is used in the preparation of primary amines. It is used as a precursor to prepare anthraquinone, phthalein, rhodamine, phthalocyanine, fluorescein and xanthene dyes. It serves as an important intermediate in the plastics industry, dyes, resins and pigments. It is used as a monomer for synthetic resins such as glyptal, alkyd resins and polyester resins. It plays a vital role in the large-scale production of plasticizers for plastics. Further, it acts as a curing agent for epoxy resins, anti-scaling agents, plating agents, surface treating agents, ion exchange agents, paint additives, adhesives, sealant chemicals and potential antibacterial agent.
This Thermo Scientific brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific.
