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

Description

Fmoc-(S)-2-(Aminomethyl)-4-methylpentanoic acid is a specialized amino acid derivative designed for solid-phase peptide synthesis. The Fmoc group enables orthogonal protection, while the branched aliphatic side chain offers enhanced solubility and reduced aggregation during coupling steps. This scaffold integrates seamlessly into complex peptide sequences, providing a stable, moisture-tolerant building block for bioactive molecule development.

Application

Fmoc-(S)-2-(Aminomethyl)-4-methylpentanoic acid serves as a versatile building block for peptide synthesis, enabling the incorporation of side-chain functionalized amino acids with enhanced solubility and stability. The Fmoc group provides orthogonal protection for the α-amino function, while the pendant primary amine facilitates conjugation or further derivatization. Its branched aliphatic structure improves metabolic stability and offers favorable steric profile for use in bioactive peptide scaffolds.
