    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

BnO-PEG4-OH is a water-soluble, bench-stable linker featuring a benzyl ether-protected hydroxyl group at one terminus and a terminal hydroxyl at the other. This dual-functional architecture enables efficient conjugation in synthetic workflows, particularly in peptide modification and bioconjugation applications where orthogonal protection strategies are required.

Application

BnO-PEG4-OH serves as a versatile, bench-stable linker for the construction of bioconjugates and functionalized polymers. Its terminal hydroxyl group enables straightforward derivatization via esterification or ether formation, while the benzyloxy-protected PEG4 chain offers excellent solubility and controlled hydrophilicity. This compound functions as a reliable spacer in peptide modification, glycoconjugate synthesis, and the preparation of polymeric drug delivery systems.
