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+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

DTPA-tetra (t-Bu ester) features four tert-butyl ester groups that enhance solubility and stability in organic solvents. This derivative enables efficient chelation of metal ions under mild conditions, with the bulky t-Bu groups offering steric protection against hydrolysis. The compound serves as a robust precursor for functionalized DTPA derivatives in radiolabeling and coordination chemistry applications.

Application

DTPA-tetra (t-Bu ester) serves as a protected derivative of DTPA, enabling convenient handling and storage while preserving the chelating functionality essential for lanthanide and heavy metal complexation. The tert-butyl ester groups offer enhanced bench stability and facilitate purification by standard chromatographic methods. This derivative functions as a versatile building block in the synthesis of radiolabeled probes and contrast agents, where orthogonal deprotection allows selective release of free DTPA under mild acidic conditions.
