    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

Boc-N-PEG1-C2-NHS ester delivers a short, hydrophilic PEG spacer flanked by a stable Boc-protected amine and a reactive NHS ester. This combination enables efficient conjugation to primary amines under physiological conditions while maintaining solubility and stability in aqueous environments.

Application

Boc-N-PEG1-C2-NHS ester serves as a versatile bifunctional linker for peptide and biomolecule conjugation. The NHS ester group readily reacts with primary amines under physiological conditions, while the Boc-protected amine enables subsequent deprotection and further functionalization. Its PEG1 spacer provides enhanced solubility and reduced aggregation, making it ideal for bioconjugation workflows requiring stability, ease of purification, and compatibility with standard synthetic protocols.
