    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

N-Boc-N-bis(PEG2-acid) features two PEG2-acid chains tethered to a Boc-protected amine, delivering enhanced solubility and stability in aqueous environments. This bifunctional reagent enables efficient conjugation workflows under standard conditions, particularly valuable in peptide derivatization and bioconjugate synthesis.

Application

N-Boc-N-bis(PEG2-acid) serves as a versatile bifunctional building block for the synthesis of PEGylated peptides and bioconjugates. The Boc-protected amine enables orthogonal handling in multi-step syntheses, while the two terminal PEG2-carboxylic acid groups facilitate efficient coupling to primary amines or surface-bound nucleophiles. This structure offers enhanced solubility, stability, and ease of purification in aqueous and mixed solvent systems, making it ideal for applications requiring controlled conjugation and improved pharmacokinetic profiles.
