    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

Propargyl-PEG4-CH2CH2-Boc features a terminal alkyne for click chemistry, flanked by a hydrophilic PEG4 spacer and a stable Boc-protected amine. This bifunctional scaffold enables efficient conjugation while maintaining solubility and compatibility with standard synthetic workflows.

Application

Propargyl-PEG4-CH2CH2-Boc serves as a versatile bifunctional linker for conjugation and protection strategies in synthetic chemistry. The propargyl group enables efficient copper-catalyzed azide-alkyne cycloaddition (CuAAC), while the Boc-protected amine offers orthogonal handling. The PEG4 spacer provides solubility and reduces aggregation, enhancing utility in peptide modification, probe synthesis, and macrocyclic scaffold construction.
