HazMat Fee

An item is classified as a dangerous good if our website displays Hazardous Material (HazMat) information for it. There is a HazMat shipping fee for each item that qualifies as a dangerous good, except in the following scenarios:

The shipment is processed through FedEx Ground under the Limited Quantity option.

Each bottle is packed as an Excepted Quantity, with a maximum of 1g for items in class 6.1 packing group I or II, and up to 25g for all other hazardous materials.

If shipping is charged to your FedEx account, the HazMat fee will be billed directly by the courier. Otherwise, the fee will be included on your invoice. To help you avoid the HazMat fee, we can package a 5g order of a class 6.1 packing group I or II material as five separate 1g units, and a 100g order of any other dangerous good as four 25g units. This packaging adjustment will be made unless you instruct otherwise on your purchase order. Below, you will find the fee schedule from FedEx for handling hazardous materials.

Description

Ethyl 2-methyl-3-oxopentanoate is a β-keto ester featuring a sterically hindered methyl group adjacent to the carbonyl, enhancing its stability under standard conditions. This structural motif enables efficient enolization and facilitates aldol-type condensations in synthetic sequences. The molecule integrates readily into complex molecular architectures due to its dual electrophilic centers and favorable reactivity profile.

Application

Ethyl 2-methyl-3-oxopentanoate serves as a versatile β-keto ester scaffold for multistep synthesis, enabling efficient construction of substituted cyclohexanones and heterocyclic frameworks via Claisen condensations, aldol reactions, and Michael additions. Its bench-stable nature, predictable enolization behavior, and compatibility with diverse functional groups facilitate reliable access to complex carbocyclic and heterocyclic intermediates in medicinal chemistry and natural product synthesis.
