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

Cl-C6-PEG4-O-CH2COOH features a chlorinated phenyl group linked via a four-ethylene glycol chain to a carboxylic acid terminus. This bifunctional construct combines halogen-directed coupling potential with hydrophilic PEG spacing and a reactive carboxyl handle for bioconjugation or surface immobilization under standard conditions.

Application

Cl-C₆-PEG₄-O-CH₂COOH serves as a versatile bifunctional linker for conjugation and solid-phase synthesis. The chloroaryl group enables efficient coupling with nucleophilic amines, while the terminal carboxylic acid facilitates amide bond formation. Its PEG4 spacer provides solubility and reduces aggregation, enhancing performance in bioconjugation and peptide chemistry workflows.
