    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

NH2-PEG7 features a linear polyethylene glycol chain with seven ethylene oxide units, terminating in a primary amine. This bifunctional scaffold enables site-specific conjugation in bioconjugation workflows, offering enhanced solubility and stability in aqueous environments.

Application

NH₂-PEG₇ serves as a versatile bifunctional linker enabling efficient conjugation in peptide and biomolecule synthesis. Its seven-ether unit provides enhanced solubility and stability in aqueous and organic media, while the terminal amine facilitates reliable coupling reactions with carboxylic acids or activated esters. Ideal for building PEGylated compounds, this reagent offers predictable behavior, ease of purification, and compatibility with standard bench-scale protocols.
