    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

Azide-PEG3-Tos features a trifunctional PEG3 spacer linking an azide group to a tosylate leaving group, enabling efficient bioorthogonal conjugation and orthogonal functionalization. This bifunctional scaffold facilitates site-specific labeling in complex biological systems under mild conditions.

Application

Azide-PEG3-Tos serves as a versatile bifunctional linker for bioconjugation and polymer chemistry, combining the stability of a tosylate leaving group with the orthogonal reactivity of an azide. The PEG3 spacer provides enhanced solubility and reduced steric hindrance, enabling efficient coupling in aqueous or mixed solvents. Its bench-stable nature facilitates straightforward handling and purification, making it ideal for constructing functionalized scaffolds in drug delivery systems and chemical biology applications.
