    Product Description

    Adipic Acid CAS 124-04-9, also called hexanedioic acid, is a C6 dicarboxylic acid with the molecular formula C6H10O4 and EINECS 204-673-3.

    Synonyms: Hexanedioic acid; 1,4-Butanedicarboxylic acid; Adipinic acid; Fatty acid diacid; Hexane-1,6-dioic acid.

    CAS: 124-04-9.

    Molecular formula: C6H10O4.

    It is supplied as white crystalline powder or granules with an assay of not less than 99.8%.

    The melting point is about 151.5-153.5 °C, moisture not more than 0.2%, and ash not more than 0.001%.

    Iron (Fe) content is not more than 0.2 ppm and platinum-cobalt color not more than 5.

    The largest use is as a monomer for nylon 66, made by polycondensation with hexamethylenediamine.

    In polyurethanes it is used for polyester polyols in flexible and rigid foams, TPU elastomers, coatings, and adhesives.

    In plasticizers it is a raw material for adipate esters such as DOA and DIDA, providing low-temperature flexibility in PVC.

    In industrial additives it is used in wet-strength paper resins, flue-gas desulfurization buffering, and specialized lubricants.

    Store in a cool, dry, well-ventilated area away from heat sources and strong oxidizing agents, with bags tightly sealed.

    Avoid dust formation during charging or discharging and maintain adequate ventilation to keep airborne concentrations low.

    Use safety glasses with side shields, PVC or nitrile gloves, and a P2 or N95 dust respirator when handling powder in bulk.

    Every batch is analyzed by gas chromatography for organic purity and atomic absorption spectroscopy for trace metals.

    Particle size distribution and moisture are controlled to ensure free-flowing material for continuous polymerization and industrial synthesis.

    Confirm appearance, assay, melting point, moisture, ash, iron, color, and grade as required.

    FAQ - Technical & Supply Chain

    • Q:

      What is Adipic Acid CAS 124-04-9?

      A: CAS 124-04-9 is adipic acid, also called hexanedioic acid or 1,4-butanedicarboxylic acid, with the molecular formula C6H10O4. This product is a white crystalline dicarboxylic acid supplied in industrial or technical grade.
    • Q:

      What are the typical physical properties of industrial-grade adipic acid?

      A: It is normally a white crystalline powder or granule with a melting point near 151-155 degrees C. The solid has low solubility in cold water but dissolves more readily in hot water, and it can form combustible dust if finely dispersed.
    • Q:

      How is Adipic Acid CAS 124-04-9 mainly used in industry?

      A: The largest use is as a monomer for nylon 66, produced by polycondensation with hexamethylenediamine. It is also used to make polyester polyols for polyurethane elastomers, foams, coatings, and adhesives, as well as adipate ester plasticizers.
    • Q:

      Can this adipic acid grade be used in polyurethane and plasticizer applications?

      A: Yes. The technical/industrial grade is suitable as a raw material for polyester polyols and for adipate esters such as DOA and DIDA. For highly regulated end uses, confirm the applicable purity, moisture, and trace-metal specifications with your downstream process.
    • Q:

      What handling precautions apply to adipic acid powder?

      A: Avoid creating airborne dust and use local exhaust ventilation in powder-handling areas because combustible dust can form explosive mixtures. Standard chemical handling practice also includes eye, skin, and respiratory protection to reduce irritation risk.
