    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

NH-bis(PEG2-propargyl) features two PEG2 chains linked to a central nitrogen, delivering enhanced solubility and biocompatibility. The terminal propargyl groups enable efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC), facilitating site-specific conjugation in bioorthogonal labeling and polymer functionalization workflows under standard conditions.

Application

NH-bis(PEG2-propargyl) serves as a versatile, bifunctional linker for conjugation and polymer synthesis, combining two propargyl groups attached to a PEG2 spacer. Its terminal alkyne functionalities enable efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC), facilitating site-specific bioconjugation and modular scaffold assembly. The PEG2 backbone imparts enhanced solubility and stability in aqueous media, while the bis-propargyl motif enables orthogonal functionalization in multi-step syntheses. Ideal for building complex architectures in drug discovery and materials science.
