25550-51-0 Usage


Methylhexahydrophthalic anhydride (MHHPA) is a cyclic dicarboxylic anhydride that serves as a curing agent and an allergen. It is the cyclic anhydride of methylhexahydrophthalic acid and is characterized by its colorless, clear appearance. MHHPA is known for its cycloaliphatic structure, which lacks aromatic bonds, metals, or contaminants, providing it with unique properties.


Used in Electric/Electronics Industry:
Methylhexahydrophthalic anhydride is used as a hardener for hot-cured epoxy resins, enhancing the performance and durability of electronic components.
Used in Polyurethane/Polyester Resins:
MHHPA is utilized as a raw material in the production of polyurethane and polyester resins, contributing to their structural integrity and performance.
Used in Adhesives:
As a component in adhesive formulations, MHHPA improves the bonding strength and durability of the final product.
Used in LEDs:
MHHPA is used in the manufacturing of high-performance LEDs, taking advantage of its UV radiation and atmospheric resistance properties.
Used in Outdoor High Voltage Castings and Composites:
MHHPA is employed in the production of outdoor high voltage castings and composites, where its resistance to UV radiation and atmospheric agents is crucial.
Used in Automotive Clear Coats:
Methylhexahydrophthalic anhydride is used as a component in automotive clear coats, providing excellent color retention and protection against environmental factors.
Used in Insecticide:
MHHPA is also utilized in the formulation of insecticides, leveraging its chemical properties to effectively control pests.
Used in Plasticizer and Antirust Applications:
The anhydride is used in the production of plasticizers and antirust agents, enhancing the performance and longevity of materials in various applications.


Methyl hexahydrophthalic anhydride is produced from methyl tetrahydrophthalic anhydride by catalytic hydrogenation. It is a high-performance product among acid anhydride-type solidifying agent.

Flammability and Explosibility



MHHPA must be stored away from open flames or other potential ignition sources, and should be protected from moisture, because it easy crystallizes when it's in contact with the humidity of the air. When some crystallization occurs, check the properties before reusing.

Check Digit Verification of cas no

The CAS Registry Mumber 25550-51-0 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,5,5,5 and 0 respectively; the second part has 2 digits, 5 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 25550-51:
100 % 10 = 0
So 25550-51-0 is a valid CAS Registry Number.
