ACETIC ANHYDRIDE Supplier in Malaysia
- Also known as
- Acetic Acid Anhydride
- Acetic Acid, 1,1'-Anhydride
ACETIC ANHYDRIDE supplier in Malaysia for cellulose-acetate, pharmaceutical, fine-chemical and industrial synthesis buyers. This clear colourless liquid, CAS 108-24-7 and formula C4H6O3, is an acetylating reagent and intermediate rather than a grade of acetic acid.
Industrial, high-purity and synthesis grades differ in assay, acetic acid, water, colour and impurity controls. Moisture changes the effective reagent composition, so buyers should state their water limit and process specification rather than relying only on a general purity label.
Manufacturers use acetic anhydride in cellulose acetate, acetylated polymer, pharmaceutical, dye, fragrance and specialty intermediate production. Acetic acid, acetate salts and acetate solvents such as ethyl acetate are separate products and are not included as grades on this page.
Send the required grade, assay, water and impurity limits, application, quantity and delivery location with your enquiry. Availability, packing, documentation and delivery timing are confirmed with the quotation. Supply is subject to applicable requirements.

ACETIC 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 |
|---|---|---|---|---|
| Industrial-grade acetic anhydride | clear colourless liquid | — | Acetylation and intermediate manufacture for cellulose acetate, acetate chemistry and other large-scale industrial processes. | Confirm the required pack format with the quotation. |
| High-purity acetic anhydride | clear colourless low-moisture liquid | — | Fine-chemical and controlled synthesis work where the buyer sets tighter assay, acetic acid, water, colour and impurity limits. | Confirm the required pack format with the quotation. |
| Pharmaceutical and reagent synthesis grade | clear colourless liquid made to a defined synthesis specification | — | Pharmaceutical, laboratory and specialty intermediate routes that name acetic anhydride as the acetylating reagent and require supporting documents. | Confirm the required pack format with the quotation. |

Safety and handling
Keep acetic anhydride tightly sealed and dry in a cool, well-ventilated area, protected from moisture, heat and incompatible materials. Follow the safety and handling information for the quoted grade. Supply is subject to applicable requirements.
Common questions about ACETIC ANHYDRIDE
Is acetic anhydride the same as acetic acid?
No. Acetic anhydride and acetic acid are separate chemical products with different formulas, reactivity and process roles. Order the exact substance named in the reaction or raw-material specification.
Which acetic anhydride grade should a buyer request?
Industrial grade suits large-scale acetylation and cellulose-acetate work, while high-purity or synthesis grade is used when water, acetic acid, colour and impurity limits are tighter. Provide the receiving specification with the enquiry.
Why does water content matter for acetic anhydride?
Moisture reacts with acetic anhydride and changes the effective reagent composition. Processes with tight reaction control should state their water and acetic-acid limits and use suitable dry handling arrangements.
What is acetic anhydride used for in cellulose acetate manufacture?
It acts as the acetylating reagent in converting cellulose to cellulose acetate. The required grade depends on the production route and its limits for assay, water, acetic acid, colour and other impurities.
Are acetate salts or acetate solvents included on this page?
No. Sodium acetate, calcium acetate, ethyl acetate and butyl acetate are separate products with different identities. This page covers acetic anhydride only.
What packing and documents are available for acetic anhydride?
Pack format and supporting documents depend on the grade and supply arrangement. Send the preferred pack and document list so they can be confirmed with the quotation.
What details are needed for an acetic anhydride price in Malaysia?
Send the grade, assay, water and impurity limits, application, quantity and delivery location. Pricing is issued on enquiry with a stated validity period, and delivery timing is confirmed in the offer.
