Succinic Anhydride Supplier in Malaysia
- Also known as
- SAH
- Dihydro-2,5-Furandione
- Butanedioic Anhydride
- Succinyl Oxide
Succinic anhydride supplier for resin, intermediate and speciality chemical buyers in Malaysia. Also known as SAH, dihydro-2,5-furandione, butanedioic anhydride and succinyl oxide (CAS 108-30-5, C4H4O3), this cyclic anhydride is distinct from succinic acid, maleic anhydride and alkenyl succinic anhydride sizing agents.
Commercial forms include technical flakes or briquettes, free-flowing powder and higher-purity crystalline material. Moisture control is important because the anhydride hydrolyses to succinic acid in water. Buyers should state form, target purity and any moisture limit with the enquiry.
Typical uses include alkyd and polyester resin modification, epoxy co-reaction, pharmaceutical and agrochemical intermediate synthesis, and building blocks for surfactant and lubricant additives. Paper-sizing chemistry that uses ASA or related alkyl succinic anhydrides refers to separate substituted products, not this page.

Succinic Anhydride grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Technical grade succinic anhydride flakes | white to off-white flakes or briquettes | — | Alkyd and polyester resin modification, epoxy curing formulations and general industrial intermediate work where bulk handling of solid anhydride is preferred. | Confirm the required pack format with the quotation. |
| Succinic anhydride powder | crystalline powder | — | Charging and dissolution in surfactant, lubricant-additive and speciality chemical synthesis where a free-flowing solid improves metering and mix-in. | Confirm the required pack format with the quotation. |
| High-purity succinic anhydride | white crystalline solid, flakes or powder | — | Pharmaceutical and agrochemical intermediate routes and other synthesis work that needs tighter purity and moisture control than a standard technical grade. | Confirm the required pack format with the quotation. |

Succinic Anhydride applications
Safety and handling
Keep sealed in a cool, dry place and protect from moisture, which converts the anhydride to succinic acid. Control dust, avoid contact with skin and eyes, and follow the safety information for the grade quoted.
Common questions about succinic anhydride
Is succinic anhydride the same as succinic acid?
No. Succinic anhydride is the cyclic anhydride of succinic acid and reacts as an anhydride intermediate. Contact with water converts it to succinic acid, which is a different commercial product. State the anhydride clearly if that is the form required.
How does succinic anhydride differ from maleic anhydride?
Maleic anhydride is the unsaturated analogue and is a different chemical with its own CAS and reactivity profile. Do not substitute one for the other without process review. Enquiries for succinic anhydride should name this product, not maleic anhydride.
Is succinic anhydride the same as ASA paper-sizing agent?
No. Alkenyl succinic anhydride (ASA) and related alkyl succinic anhydrides are substituted derivatives used in paper sizing and are not this unsubstituted product. If the requirement is ASA or OSA, name that product separately rather than requesting succinic anhydride alone.
Which form of succinic anhydride should I request?
Flakes or briquettes are common for bulk resin and intermediate charging. Powder suits metering in synthesis and additive manufacture. High-purity material is selected when pharmaceutical or fine-chemical routes need tighter controls. State the form, target purity and moisture preference with the enquiry.
Why does moisture control matter for succinic anhydride?
The anhydride hydrolyses to succinic acid when exposed to water or humid air, which changes identity and performance in anhydride-dependent reactions. Keep material sealed and dry in storage and handling, and include any moisture limit in the specification.
What details are needed for a succinic anhydride price enquiry?
Provide the form or grade, target assay or purity, application, quantity and delivery location. Mention preferred packing, documentation needs and timing so the quotation can cover the full commercial requirement.
