    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-PEG4-CH2CH2COOH features a linear PEG4 spacer flanked by an amine handle and a terminal carboxylic acid, enabling dual conjugation versatility. This bifunctional linker facilitates site-specific coupling in bioconjugation workflows, offering enhanced solubility and stability under physiological conditions.

Application

NH₂-PEG₄-CH₂CH₂COOH serves as a versatile bifunctional linker for conjugation workflows, combining the solubility and stability of a tetra(ethylene glycol) chain with orthogonal reactive handles. The terminal amine enables efficient coupling to carboxylated surfaces or biomolecules, while the β-carboxylic acid facilitates further derivatization via amide or ester formation. Its well-defined structure supports reliable purification and consistent performance in peptide, antibody-drug conjugate, and nanoparticle functionalization applications.
