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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+

Description

Amino-PEG7-amine features a central polyethylene glycol chain of seven ethylene oxide units, flanked by primary amine groups at both termini. This bifunctional architecture enables efficient conjugation in bioconjugation workflows, offering enhanced solubility and flexibility for applications in drug delivery, polymer chemistry, and surface functionalization.

Application

Amino-PEG7-amine serves as a versatile bifunctional linker for conjugation and polymer functionalization. Its seven-ethylene glycol units provide enhanced solubility and reduced aggregation, while the terminal primary amines enable efficient coupling to carboxylate or activated ester groups. The molecule exhibits excellent stability under standard bench conditions and facilitates purification via precipitation or dialysis. Widely used in bioconjugation, drug delivery systems, and surface modification, it functions reliably across diverse synthetic workflows.
