    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

CH2COOH-PEG3-CH2COOH features two carboxylic acid termini flanking a triethylene glycol spacer, enabling versatile conjugation in bioconjugation and polymer chemistry. This bifunctional linker offers enhanced solubility and controlled spacing, facilitating efficient coupling to biomolecules or surfaces under standard conditions.

Application

CH2COOH-PEG3-CH2COOH serves as a bifunctional linker enabling efficient conjugation in peptide and biomolecule synthesis. The terminal carboxylic acid groups facilitate amide bond formation under standard coupling conditions, while the PEG3 spacer provides solubility enhancement and reduced aggregation. This structure offers excellent stability, ease of purification, and compatibility with diverse functional groups, making it well-suited for applications in drug delivery, diagnostic labeling, and polymer chemistry.
