    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

Aminooxy-PEG1-propargyl delivers a reactive alkyne handle flanked by a stable PEG spacer and a nucleophilic aminooxy group. This bifunctional linker enables site-specific conjugation via oxime ligation and click chemistry, facilitating efficient bioconjugation under physiological conditions.

Application

Aminooxy-PEG1-propargyl serves as a versatile bifunctional linker for bioconjugation and click chemistry applications. The propargyl group enables efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC), while the aminooxy moiety facilitates oxime ligation with aldehydes or ketones. Its PEG1 spacer provides enhanced solubility and reduced non-specific binding, making it ideal for labeling biomolecules, constructing polymer-drug conjugates, and synthesizing functionalized surfaces with high stability and ease of purification.
