    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

Bis-propargyl-PEG11 features two terminal propargyl groups flanking an 11-ethylene glycol unit, enabling efficient copper-catalyzed azide-alkyne cycloaddition. This bifunctional linker offers enhanced solubility in aqueous and organic media, facilitating conjugation workflows in bioconjugation and polymer synthesis.

Application

Bis-propargyl-PEG11 serves as a versatile, linear spacer for click chemistry applications, enabling efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC) at both termini. Its PEG backbone provides enhanced solubility and biocompatibility, while the terminal propargyl groups offer high reactivity and stability under standard bench conditions. Ideal for synthesizing dendrimers, cross-linking polymers, or constructing bioconjugates with precise spacing and functional group tolerance.
