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

tert-Butyl piperazine-1-carboxylate oxalate serves as a bench-stable, moisture-tolerant derivative that simplifies the handling of piperazine intermediates. The oxalate counterion enhances crystallinity and solubility in common organic solvents, enabling efficient incorporation into multi-step syntheses. This formulation facilitates clean deprotection and functionalization workflows in medicinal chemistry and process development.

Application

tert-Butyl piperazine-1-carboxylate oxalate serves as a stable, bench-ready precursor for piperazine derivatives, enabling efficient deprotection under mild acidic conditions. Its oxalate salt form enhances solubility and crystallinity, facilitating purification and handling. The compound functions as a key building block in medicinal chemistry, supporting the synthesis of heterocyclic scaffolds through standard coupling and functionalization protocols.
