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 4-(4-aminophenyl)piperazine-1-carboxylate features a piperazine core linked to a para-aminophenyl group, delivering a robust scaffold for medicinal chemistry. The tert-butyl ester moiety enhances solubility and stability while enabling straightforward deprotection under mild acidic conditions. This compound serves as a key intermediate in the synthesis of bioactive molecules, particularly those targeting CNS disorders and kinase pathways.

Application

tert-Butyl 4-(4-aminophenyl)piperazine-1-carboxylate serves as a versatile building block for the synthesis of biologically active piperazine-based compounds. Its robust tert-butoxycarbonyl (Boc) group offers excellent bench stability and facilitates straightforward deprotection under mild acidic conditions. The pendant aniline functionality enables direct coupling reactions, including Suzuki-Miyaura, Ullmann, and reductive amination, making it ideal for constructing diverse heterocyclic scaffolds and drug candidates in medicinal chemistry workflows.
