Ethanoic Anhydride
Ethanoic Anhydride (Product Code: SCI-435/182), also known as acetic anhydride, is an analytical reagent grade acetylating agent used to prepare compounds such as aspirin in college and advanced school organic chemistry laboratories. It comes in a 250 ml pack with an MSDS, for departments that run acylation practicals. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier in India for teaching and research laboratories.

What Is Ethanoic Anhydride Used For?
Ethanoic anhydride transfers an ethanoyl (acetyl) group to alcohols, phenols and amines. Its main teaching use is the synthesis of aspirin from salicylic acid, where it is preferred to ethanoic acid because the reaction goes much further towards completion and the by-product is simply ethanoic acid. In college organic courses it is also used to acetylate phenylamine (aniline), a standard acylation followed by recrystallisation of the product.
The reagent reacts with water to form ethanoic acid, so keep the bottle tightly closed and use dry glassware. The liquid and its vapour are corrosive and irritating to the eyes and airways; dispense it in a fume cupboard wearing gloves and goggles, and follow the MSDS supplied for storage and first aid.
Supplier
ScienceLab — the trading name of Jain Scientific Equipments Private Limited — supplies ethanoic anhydride to teaching and research laboratories that need it for acylation practicals, and can quote the related glassware on the same enquiry. Ethanoic anhydride is a regulated chemical in many countries, so please tell us the intended use and delivery location when you enquire.

Frequently Asked Questions
Is Ethanoic Anhydride the same as acetic anhydride?
Yes. Ethanoic Anhydride is the systematic name for acetic anhydride; both names describe the same compound. Our listing, SCI-435/182, is analytical reagent grade in a 250 ml pack and is supplied with an MSDS for safe handling.
What is Ethanoic Anhydride used for in teaching labs?
Ethanoic Anhydride is mainly used to acetylate salicylic acid in the aspirin synthesis practical, and in college courses to acetylate amines such as phenylamine. It reacts more completely than ethanoic acid, which gives students more product to purify and analyse.
How should Ethanoic Anhydride be stored?
Store Ethanoic Anhydride in its tightly closed original bottle in a cool, dry, ventilated chemical store, away from water, alcohols, strong bases and oxidisers. Moisture slowly converts it to ethanoic acid, so close the bottle straight after dispensing. The MSDS gives full details.
What is the shelf life of Ethanoic Anhydride?
Shelf life depends on the chemical, its grade and storage conditions, and moisture affects this reagent in particular. Ask us for the expiry date of the batch of Ethanoic Anhydride you are quoted, and use opened bottles promptly.
Are there restrictions on buying Ethanoic Anhydride?
Ethanoic Anhydride is a regulated chemical in many countries, including India, because it can be misused. Please state the intended use, the buying institution and the delivery location when you enquire through the contact page, so the required documentation can be discussed before supply.
Who supplies Ethanoic Anhydride?
Ethanoic Anhydride (SCI-435/182) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to schools, colleges, research laboratories, dealers and importers in India and international markets, subject to the documentation the chemical requires.
