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

(R)-1-Boc-2-ethyl-piperazine is a chiral piperazine derivative featuring a Boc-protected amine and an ethyl substituent at the 2-position. This bench-stable, moisture-tolerant scaffold integrates readily into asymmetric synthesis workflows, enabling efficient access to bioactive alkaloids and pharmaceutical intermediates through selective deprotection and coupling reactions.

Application

(R)-1-Boc-2-ethyl-piperazine serves as a stereochemically defined building block for the synthesis of bioactive piperazine-based scaffolds. The Boc group provides orthogonal protection, enabling selective deprotection under mild acidic conditions. Its ethyl substituent enhances lipophilicity and modulates solubility, while the piperazine core facilitates diverse functionalization—ideal for medicinal chemistry campaigns requiring precise stereocontrol and robust handling during multi-step syntheses.
