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 bench-stable, moisture-tolerant piperazine derivative features a tert-butyl-protected amine and a hydrochloride salt form, enabling straightforward incorporation into synthetic sequences. The sterically hindered backbone resists undesired side reactions, while the carboxylate moiety facilitates efficient deprotection under standard conditions.

Application

(S)-tert-Butyl 2-(tert-butyl)piperazine-1-carboxylate hydrochloride serves as a chiral piperazine building block with enhanced stability and ease of handling. Its tert-butyl protecting groups offer robustness under standard synthetic conditions, enabling selective deprotection and functionalization. The molecule facilitates efficient access to pharmaceutically relevant scaffolds through amine coupling, reductive amination, and metal-catalyzed transformations, making it a practical choice for medicinal chemistry campaigns requiring stereocontrol and scalable synthesis.
