    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

m-PEG2-CH2CH2COOH features a methoxy-terminated PEG2 chain linked to a reactive carboxylic acid group, enabling efficient conjugation in bioconjugation workflows. This bifunctional architecture combines hydrophilic stability with site-specific coupling potential, facilitating use in peptide modification, nanoparticle functionalization, and probe synthesis under mild aqueous conditions.

Application

m-PEG2-CH2CH2COOH serves as a versatile bifunctional linker for conjugation and polymer synthesis, combining the solubility and stability of a short PEG chain with a reactive carboxylic acid group. It enables efficient amide bond formation under standard coupling conditions, facilitating site-specific attachment to amines in peptides, proteins, or biomolecules. The molecule exhibits excellent bench stability and ease of purification, making it well-suited for use in diagnostic labeling, drug delivery systems, and solid-phase synthesis.
