    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

Ms-PEG2-C2-Boc features a protected amine handle at the terminus of a two-unit polyethylene glycol spacer, enabling efficient conjugation in bioconjugation workflows. The Boc group provides orthogonal protection, while the PEG linker enhances solubility and reduces aggregation during synthesis. This derivative supports modular peptide and biomolecule modification under standard conditions.

Application

Ms-PEG2-C2-Boc serves as a versatile bifunctional linker for peptide and biomolecule conjugation, combining the stability of a Boc-protected amine with a maleimide-tethered PEG spacer. The sulfonamide (Ms) group enables selective N-alkylation under mild conditions, while the PEG2 chain provides enhanced solubility and reduced aggregation. This reagent facilitates efficient conjugation to cysteine residues via Michael addition, offering excellent stability, ease of purification, and compatibility with standard synthetic workflows in medicinal chemistry and bioconjugate applications.
