    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

Azido-PEG8-acid features a terminal azide group and carboxylic acid functionality separated by an eight-ethylene glycol spacer. This bifunctional linker enables site-specific conjugation via click chemistry while providing aqueous solubility and reduced non-specific binding. Ideal for bioconjugation applications requiring stability and controlled presentation.

Application

Azido-PEG8-acid serves as a versatile bifunctional linker for bioconjugation and polymer chemistry, enabling efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC) due to its terminal azide group. The PEG8 spacer provides enhanced solubility and reduced non-specific binding, while the carboxylic acid functionality facilitates amide coupling with amines under standard activation conditions. This compound offers excellent bench stability, simplifies purification via precipitation or chromatography, and functions reliably in the synthesis of targeted conjugates and functionalized polymers.
