Product Details
Ethyl acetate (systematically ethyl ethanoate, commonly shortened to EtOAc or EA) is an organic compound with the molecular formula CH3COOCH2CH3. This clear liquid features a distinct sweet scent reminiscent of pear drops. It is widely used in adhesives, nail polish removers, decaffeination of tea and coffee, and as an additive in cigarettes. Ethyl acetate is the ester formed from ethanol and acetic acid and is produced industrially on a large scale for use as a versatile solvent. In 1985, the combined annual output in Japan, North America, and Europe reached approximately 400,000 tons. By 2004, global production was estimated at 1.3 million tons.

Product Application
In pharmaceutical preparations, ethyl acetate serves mainly as a solvent, though it is also employed as a flavoring agent. As a solvent, it appears in topical solutions, gels, and edible printing inks for tablets. It has been found to boost the solubility of chlortalidone and modify polymorphic crystal structures of piroxicam pivalate, mefenamic acid, and fluconazole. It is used in microsphere formulations and in manufacturing liposomal amphotericin B dry powder inhalers. Studies have also explored its role as a chemical penetration enhancer for transdermal iontophoresis of insulin.
In food applications, ethyl acetate is primarily used as a flavoring agent. It is also included in artificial fruit essences and acts as an extraction solvent during food processing.
