    Product Description

    UV Absorber UV-P CAS 2440-22-4 is 2-(2H-benzotriazol-2-yl)-p-cresol (2-(2H-benzotriazol-2-yl)-4-methylphenol), with molecular formula C13H11N3O.

    Synonyms: UV Absorber UV-P; UV-P; 2-(2H-benzotriazol-2-yl)-p-cresol; 2-(2H-benzotriazol-2-yl)-4-methylphenol.

    CAS: 2440-22-4.

    Molecular formula: C13H11N3O.

    It is normally supplied as a light-yellow crystalline powder.

    It is used as a benzotriazole UV absorber in polymer and coating systems.

    It is used in plastics, masterbatch, coatings, adhesives and sealants.

    It is also used in stabilizer packages with antioxidants and other stabilizers.

    Performance depends on formulation compatibility, processing temperature and the required stabilizer package.

    Grades are selected by assay, melting range, colour and volatiles.

    UV-P is not the same as 1H-Benzotriazole.

    Confirm assay, melting range, colour, volatiles, ash, particle form and transmittance requirements.

    For purchasing, specify the intended resin, coating or adhesive system and the required stabilizer package.

    Keep sealed and dry, and follow the current SDS for storage and handling.

    Use suitable PPE and exposure controls when handling the material.

    Confirm assay, melting range, colour, volatiles and ash on the COA.

    Confirm grade, packaging, and specification as required.

    FAQ - Technical & Supply Chain

    • Q:

      Is UV-P the same as 1H-Benzotriazole?

      A: No. UV-P is a substituted benzotriazole UV absorber, while 1H-Benzotriazole is commonly used in corrosion-inhibitor chemistry. Their CAS numbers, applications and formulation behaviour are different, so they should not be purchased as substitutes.
    • Q:

      What should be checked when buying UV Absorber UV-P?

      A: Confirm assay, melting range, colour, volatiles, ash, particle form, packaging and any transmittance or compatibility requirement. These controls help match the supplied grade to the intended plastic, coating, adhesive or resin formulation.
    • Q:

      Can UV-P be used alone as a complete stabilizer package?

      A: Not always. UV-P absorbs ultraviolet light, but many polymer systems also need antioxidants, HALS or other stabilizers. The complete package should be validated in the actual formulation and processing conditions.
