    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

CbzNH-PEG3-OH features a carbamoyl-protected amine linked to a triethylene glycol spacer, offering enhanced solubility and stability in aqueous and organic media. This hydrophilic, bench-stable derivative enables efficient conjugation workflows in peptide synthesis and bioconjugation chemistry.

Application

CbzNH-PEG3-OH serves as a versatile bifunctional linker for peptide and polymer synthesis, combining the stability of Cbz protection with the solubility and chain flexibility of triethylene glycol. The primary amine enables conjugation via standard amide coupling, while the terminal hydroxyl facilitates further derivatization or purification. Its bench-stable nature and compatibility with common reaction conditions make it ideal for iterative synthesis workflows in medicinal chemistry and materials science.
