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+
Inaccessible (Haz class 6.1 or 9), International	$108.00+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

(S)-1-Boc-3-ethyl-piperazine is a chiral piperazine derivative featuring a Boc-protected amine and an ethyl substituent at the 3-position. This bench-stable, moisture-tolerant building block facilitates stereoselective synthesis of bioactive molecules, particularly in medicinal chemistry campaigns requiring defined spatial orientation.

Application

(S)-1-Boc-3-ethylpiperazine serves as a versatile chiral building block in medicinal chemistry, enabling the synthesis of bioactive molecules through standard amine functionalization and coupling reactions. Its Boc group provides excellent bench stability and orthogonal deprotection under mild acidic conditions, while the piperazine core offers favorable solubility and hydrogen-bonding capacity. The ethyl substituent enhances steric and electronic tuning for targeted receptor interactions, facilitating efficient incorporation into diverse heterocyclic scaffolds and API intermediates.
