    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-PEG6-CH2CH2COOH features a six-ethylene glycol unit spacer flanked by an amine group and a terminal carboxylic acid, enabling efficient conjugation in bioorthogonal and protein labeling workflows. The hydrophilic PEG chain enhances solubility and reduces nonspecific binding, while the functional termini support site-specific coupling under mild conditions.

Application

NH₂-PEG₆-CH₂CH₂COOH serves as a versatile bifunctional linker for conjugation workflows, combining the solubility and biocompatibility of PEG with orthogonal reactive handles. The terminal amine enables coupling to carboxylate-functionalized molecules, while the distal carboxylic acid facilitates amide bond formation with primary amines. Its well-defined structure ensures reproducible conjugation in peptide-protein bioconjugates, antibody-drug conjugates, and surface functionalization applications.
