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+

Description

N-(Tert-Butoxycarbonyl)-L-neopentylglycine features a sterically hindered neopentylglycine scaffold protected by a robust tert-butoxycarbonyl group, enabling stable incorporation into peptide synthesis workflows. This derivative facilitates efficient coupling reactions while maintaining compatibility with standard deprotection conditions.

Application

N-(Tert-Butoxycarbonyl)-L-neopentylglycine serves as a robust, bench-stable amino acid building block for peptide synthesis and medicinal chemistry. Its neopentyl side chain provides exceptional steric hindrance and metabolic stability, minimizing unwanted reactivity. The Boc group enables straightforward deprotection under mild acidic conditions, facilitating efficient coupling and purification in standard solid-phase and solution-phase workflows.
