    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(PEG4-Boc) features two PEG4-Boc protecting groups flanking a central amine, enabling dual functionalization in peptide and oligonucleotide synthesis. This bifunctional reagent offers enhanced solubility and stability under standard conditions, facilitating efficient coupling reactions while minimizing side processes.

Application

NH-bis(PEG4-Boc) serves as a bifunctional, water-soluble linker for the synthesis of peptide-drug conjugates and macrocyclic architectures. The PEG4 spacer provides enhanced solubility and reduced aggregation, while the two Boc groups enable selective deprotection under mild acidic conditions. This reagent facilitates efficient conjugation workflows and simplifies purification in solid-phase and solution-phase syntheses.
