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

N-Pht-Phe-OH is a bench-stable, moisture-tolerant amino acid derivative featuring a phthalimide-protected α-amino group and a phenylalanine side chain. This protected form enables straightforward incorporation into peptide synthesis workflows, offering reliable coupling efficiency and minimal epimerization under standard conditions.

Application

N-Pht-Phe-OH serves as a robust, bench-stable amino acid building block for peptide synthesis, enabling efficient incorporation of phenylalanine into target sequences. The phthalimide protecting group offers excellent stability during storage and standard synthetic manipulations, while permitting reliable deprotection under mild conditions. Its compatibility with common coupling reagents and tolerance to diverse functional groups make it a practical choice for both manual and automated synthesis workflows.
