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

This tetrapeptide derivative features a C-terminal ester-linked carboxylic acid, combining peptide backbone stability with enhanced solubility. The Gly-Gly-Phe-Gly sequence provides a rigid, hydrophobic core, while the N-terminal amidation and O-alkylated side chain enable controlled reactivity in bioconjugation workflows.

Application

Gly-Gly-Phe-Gly-NH-CH₂-O-CH₂COOH serves as a stable, readily accessible peptide-based building block for the synthesis of bioactive oligopeptide scaffolds. Its N-terminal hydroxymethyl carbamate functionality enables selective derivatization and conjugation in solid-phase and solution-phase peptide coupling protocols. The sequence exhibits good bench stability and facilitates orthogonal functional group manipulation, supporting efficient access to cyclic analogs and peptidomimetic architectures in medicinal chemistry campaigns.
