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+

Description

tert-Butyl (3S)-3-phenylpiperazine-1-carboxylate is a stereochemically defined piperazine derivative featuring a chiral (3S) center and a phenyl group at the 3-position. This bench-stable, moisture-tolerant building block integrates readily into medicinal chemistry campaigns targeting CNS-active compounds and GPCR modulators. The tert-butyl ester facilitates selective deprotection under mild acidic conditions, enabling efficient access to functionalized piperazine scaffolds.

Application

tert-Butyl (3S)-3-phenylpiperazine-1-carboxylate serves as a stereochemically defined building block for the synthesis of bioactive piperazine derivatives. Its tert-butyl carbamate protection enables stable handling and selective deprotection under mild acidic conditions, facilitating downstream functionalization. The phenyl-substituted piperazine core provides a rigid, polar scaffold compatible with diverse coupling reactions and functional group transformations in medicinal chemistry workflows.
