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.

Description

This tert-butyl (3R,5R)-3,5-dimethylpiperazine-1-carboxylate features a stereochemically defined piperazine core with two methyl groups at the 3- and 5-positions, providing steric shielding and enhanced metabolic stability. The tert-butyl ester group enables straightforward deprotection under mild acidic conditions, facilitating integration into complex molecular architectures. This configuration imparts favorable solubility and handling characteristics for use in medicinal chemistry campaigns targeting CNS-penetrant molecules.

Application

tert-Butyl (3R,5R)-3,5-dimethylpiperazine-1-carboxylate serves as a stereochemically defined piperazine building block, enabling the efficient construction of complex heterocyclic scaffolds in medicinal chemistry. Its tert-butyl carbamate group offers excellent bench stability and facilitates straightforward deprotection under mild acidic conditions. The 3,5-dimethyl substitution pattern enhances conformational rigidity and provides favorable steric and electronic properties for target-directed synthesis.
