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+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

H-D-Phe-OtBu·HCl is a bench-stable, moisture-tolerant dipeptide building block featuring a protected D-phenylalanine residue. This derivative enables efficient incorporation into peptide sequences under standard coupling conditions, offering enhanced solubility and reduced aggregation during synthesis workflows.

Application

H-D-Phe-OtBu·HCl serves as a stable, bench-ready building block for peptide synthesis, enabling efficient incorporation of D-phenylalanine into bioactive sequences. Its tert-butyl ester group provides orthogonal protection and facilitates straightforward deprotection under mild acidic conditions. The compound exhibits excellent functional group tolerance and purity, making it well-suited for iterative solid-phase and solution-phase methodologies in medicinal chemistry and peptide library development.
