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

Fmoc-5-Chloro-L-tryptophan integrates a chlorinated indole ring into peptide synthesis, enabling site-specific incorporation of electron-deficient tryptophan derivatives. This bench-stable reagent facilitates the introduction of halogenated functionalities for probing protein structure and function, particularly in studies requiring enhanced photoreactivity or metabolic labeling.

Application

Fmoc-5-Chloro-L-tryptophan serves as a valuable building block for peptide synthesis, enabling the incorporation of a halogenated tryptophan residue with enhanced electronic and steric properties. The Fmoc group provides reliable orthogonal protection for the amine, while the 5-chloro substitution offers a versatile handle for downstream functionalization via cross-coupling or nucleophilic substitution. Its bench-stable nature and compatibility with standard coupling protocols facilitate efficient solid-phase and solution-phase synthesis workflows.
