    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-PEG3 features a terminal amine group linked to a triethylene glycol spacer, offering enhanced solubility and stability in aqueous and organic media. This bifunctional scaffold enables efficient conjugation in bioconjugation workflows, integrating seamlessly into peptide, protein, and oligonucleotide modifications. The PEG3 chain provides steric shielding and improved pharmacokinetic properties.

Application

NH₂-PEG₃ serves as a versatile bifunctional linker in synthetic chemistry, enabling efficient conjugation of amine-containing molecules to PEGylated systems. Its three-ethylene glycol units provide enhanced solubility and stability in aqueous environments, while the primary amine facilitates straightforward coupling reactions. Ideal for bioconjugation workflows, it supports modular synthesis of drug delivery agents, diagnostic probes, and polymer-based therapeutics with predictable handling and purification advantages.
