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

Ethyl L-tryptophanate hydrochloride features a protected L-tryptophan scaffold with enhanced solubility and stability under standard conditions. This derivative integrates seamlessly into peptide synthesis workflows, enabling efficient access to biologically relevant indole-containing sequences without requiring complex purification.

Application

Ethyl L-tryptophanate hydrochloride serves as a stable, bench-ready building block for the synthesis of tryptophan-derived heterocycles and peptide analogs. Its well-defined stereochemistry and orthogonal functional groups facilitate efficient coupling reactions and selective transformations. The hydrochloride salt enhances solubility and handling, enabling straightforward incorporation into medicinal chemistry workflows and solid-phase synthesis protocols.
