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+

Description

3-(2-Thienyl)-L-alanine integrates a thienyl group at the 3-position of L-alanine, delivering a bioactive scaffold with enhanced electronic properties. This chiral building block features a planar, electron-rich heterocycle that improves π-stacking interactions in peptide architectures. The molecule exhibits bench-stable handling characteristics and is compatible with standard coupling protocols in synthetic peptide chemistry.

Application

3-(2-Thienyl)-L-alanine serves as a valuable chiral building block for the synthesis of biologically active compounds, particularly in medicinal chemistry and peptide-based drug discovery. Its thienyl group imparts enhanced metabolic stability and modulates lipophilicity, while the L-alanine backbone ensures compatibility with standard coupling protocols. The molecule exhibits good bench stability and facilitates efficient incorporation into diverse scaffolds via amide bond formation or further functionalization.
