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.

Description

Fmoc-(S)-3-Amino-3-(3-thienyl)-propionic acid is a bench-stable, moisture-tolerant amino acid derivative featuring a thiophene-containing side chain. This structure integrates a polar, electron-rich heterocycle that enhances solubility and provides a unique handle for bioconjugation. The Fmoc group enables efficient solid-phase peptide synthesis, while the chiral (S)-configuration ensures stereochemical fidelity in sequence assembly.

Application

Fmoc-(S)-3-Amino-3-(3-thienyl)-propionic acid serves as a versatile building block for peptide synthesis, enabling the incorporation of a thienyl-substituted aliphatic amino acid with enhanced aromatic character and metabolic stability. The Fmoc group ensures efficient orthogonal protection for amine-directed coupling, while the 3-thienyl moiety provides a rigid, electron-rich scaffold suitable for medicinal chemistry applications. Bench-stable and compatible with standard solid-phase protocols, it facilitates straightforward purification and high-yielding conjugation in both solution and on-resin workflows.
