It is soluble in alcohol and propylene glycol but practically insoluble in water (0.6g/L at 25°C). With a relative density of 0.865 at 25°C, it is less dense than water. It boils at 133°C and is classified as a hazardous flammable liquid (ADR Class 3, UN Number 3272, flash point 26°C). E2MB occurs naturally in fruits such as apples, pineapples, strawberries, plums, and oranges. **Odor** is powerful Sharp Sweet Fruity Green-fruity, with hints of apple and pineapple and **taste** is fruity, apple, green, minty **To be used:** - in **perfumery** for fruity, fresh volatile top notes - in **flavor** for fruity notes like apple, pineapple, and plum ## Methyl 2-methylbutyrate Synonyms of **M2MB** are **Methyl 2-methyl butanoate** and **2-methylbutyric acid**, **methyl ester**. **M2MB** appears as a colorless oily liquid with a fruity odor reminiscent of green apple. It is soluble in both alcohol and di propyleneglycol. It is slowly soluble in water ( 3.2 g/lat 25°C). Also, it is a flammable liquid (ADR Class 3, UN Number 3272, flash point 21°C) and boils at 115°C. **Odor** is fruity green-fruity, reminiscent of apple and **taste** is sweet, fruity, apple, ripe. **To be used:** - in **perfumery** for fruity, fresh volatile top notes - in **flavor** compounds for fruity notes ![](https://blog.ecsa-chemicals.ch/hs-fs/hubfs/Imported_Blog_Media/Formulas-Jun-06-2025-08-24-53-1186-AM.png?width=400&height=300&name=Formulas-Jun-06-2025-08-24-53-1186-AM.png) ### Availability & Prices **E2MB** is available in 25 kg and 180 kg plastic drums. **M2MB** is available in 25 kg and 180 kg plastic drums. #### Ask for a quotation [MP 022251](https://ecsa-chemicals.ch/en/product/mp-022251-2/)  [MP 026261](https://ecsa-chemicals.ch/en/product/mp-026261-2/)  [MP 036532](https://ecsa-chemicals.ch/en/product/mp-036532-2/) *Interested?* *Our experts are at your disposal to help to choose the right product* [Contact us](https://ecsa-chemicals.ch/en/contact/) --- #### Share: - [Follow us on Facebook](http://www.facebook.com/share.php?u=https://blog.ecsa-chemicals.ch/en/ethyl-2-methylbutyrate-and-methyl-2-methylbutyrate) - [Follow us on Twitter](https://twitter.com/intent/tweet?url=https://blog.ecsa-chemicals.ch/en/ethyl-2-methylbutyrate-and-methyl-2-methylbutyrate&text=Ethyl%202-methylbutyrate,%20Methyl%202-methylbutyrate) - [Follow us on Linkedin](http://www.linkedin.com/shareArticle?mini=true&url=https://blog.ecsa-chemicals.ch/en/ethyl-2-methylbutyrate-and-methyl-2-methylbutyrate) - [Follow us on Pinterest](http://pinterest.com/pin/create/button/?url=https://blog.ecsa-chemicals.ch/en/ethyl-2-methylbutyrate-and-methyl-2-methylbutyrate&text=Ethyl%202-methylbutyrate,%20Methyl%202-methylbutyratedescription=Ethyl%202-methylbutyrate%20(E2MB,%20CAS%20no.%207452-79-1,%20FEMA%202443)%20and%20Methyl%202-methylbutyrate%20(M2MB,%20Cas%20no.%20868-57-5,%20FEMA%202719%20)%20are%20fatty%20acid%20esters%20obtained%20by[...]&media=https://27166650.fs1.hubspotusercontent-eu1.net/hubfs/27166650/Imported_Blog_Media/Ethyl-2-methylbutyrate-e-Methyl-2-meth-1.png) #### [Dextrose - probably the best-known simple sugar Previous post](https://blog.ecsa-chemicals.ch/en/dextrose-probably-the-best-known-simple-sugar) #### [Isopropyl palmitate Next post](https://blog.ecsa-chemicals.ch/en/isopropyl-palmitate-applications) #### You might also be interested in: ### [Dextrose - probably the best-known simple sugar](https://blog.ecsa-chemicals.ch/en/dextrose-probably-the-best-known-simple-sugar) [Purchase advice ,](https://blog.ecsa-chemicals.ch/en/tag/purchase-advice) [Products](https://blog.ecsa-chemicals.ch/en/tag/products) ### [Guide to the use of hydroxy acids in cosmetic products](https://blog.ecsa-chemicals.ch/en/guide-to-the-use-of-hydroxy-acids-in-cosmetic-products) [Expert advice ,](https://blog.ecsa-chemicals.ch/en/tag/expert-advice) [Products](https://blog.ecsa-chemicals.ch/en/tag/products) ### [Sunscreen formulation strategies](https://blog.ecsa-chemicals.ch/en/sunscreen-formulation-strategies) [Expert advice ,](https://blog.ecsa-chemicals.ch/en/tag/expert-advice) [Purchase advice ,](https://blog.ecsa-chemicals.ch/en/tag/purchase-advice) [Products](https://blog.ecsa-chemicals.ch/en/tag/products) ## Stay connected ### Receive the latest information and news from the chemistry world [![ecsa chemicals](https://blog.ecsa-chemicals.ch/hubfs/ECSA_Chemicals_April2025/Images/logo.svg "ecsa chemicals")](https://ecsa-chemicals.ch/) Social Associations and partners - [RSPO](https://www.rspo.org/) - [AssICC](https://www.assicconline.it/) - [Scienceindustries](https://www.scienceindustries.ch/) - [FECC](https://www.fecc.org/) - [Sedex](https://www.sedex.com/) - [IFEAT](https://ifeat.org/) - [SEPAWA](https://www.sepawa.com/) - [Bio Suisse](https://www.bio-suisse.ch/) - [World Chemical Distributor Directory](https://chemical-distributors.com/) - [EFEO](https://www.efeo.eu/) - [Cosmetica Italia](https://www.cosmeticaitalia.it/) - [Bioagricert](https://www.bioagricert.org/) - [Farma industria](https://www.farmaindustriaticino.ch/) - [Carlo Erba Reagents](https://ecsa-chemicals.ch/en/carlo-erba-reagents/) - [Contact us](https://ecsa-chemicals.ch/en/contact/) - [Catalogs](https://ecsa-chemicals.ch/en/catalogues/) - [Suppliers](https://ecsa-chemicals.ch/en/suppliers/) - [Career](https://ecsa-chemicals.ch/en/about-us/career/) - [We Are ECSA](https://ecsa-chemicals.ch/en/about-us/we-are-ecsa/) 2026 ECSA Group.
