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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

(r)-2-((Tert-butoxycarbonyl)amino)-3,3-dimethylpent-4-enoic acid features a sterically hindered, bench-stable α,β-unsaturated carbonyl system paired with a protected amine. This configuration enables direct incorporation into peptide synthesis workflows and facilitates downstream deprotection under mild acidic conditions. The molecule’s conjugated enoate moiety supports efficient coupling reactions while maintaining stability during storage and handling.

Application

(r)-2-((Tert-butoxycarbonyl)amino)-3,3-dimethylpent-4-enoic acid serves as a versatile chiral building block for the synthesis of peptidomimetics and bioactive heterocycles. The protected amine and terminal alkyne functionalities enable efficient coupling reactions and downstream transformations, including palladium-catalyzed cross-couplings and cyclizations. Its tert-butyl carbamate group provides excellent stability and ease of purification, while the (r)-configuration ensures stereochemical fidelity in complex molecule assembly.
