    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

2-Ethyl-2-methylbutanoic acid features a sterically hindered α-carbon that enhances its resistance to decarboxylation and oxidation under standard conditions. This structural rigidity supports its use in controlled synthetic pathways, particularly where stability of the carboxylic acid moiety is critical.

Application

2-Ethyl-2-methylbutanoic acid serves as a valuable chiral building block in synthetic organic chemistry, offering a sterically hindered aliphatic carboxylic acid functionality. Its branched alkyl structure enhances metabolic stability and provides a robust scaffold for peptide mimetics and bioactive molecule synthesis. The compound exhibits good bench stability and facilitates efficient coupling reactions with minimal racemization, enabling straightforward incorporation into complex architectures via standard amide bond formation protocols.
