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 4-(4-hydroxyphenyl)piperazine-1-carboxylate features a piperazine core functionalized with a para-hydroxyphenyl group and a tert-butyl ester, delivering a bench-stable, moisture-tolerant scaffold for medicinal chemistry. This compound integrates readily into diverse synthetic routes, enabling efficient access to bioactive molecules through straightforward deprotection or coupling reactions.

Application

tert-Butyl 4-(4-hydroxyphenyl)piperazine-1-carboxylate serves as a versatile building block in medicinal chemistry, enabling efficient access to piperazine-based scaffolds. The pendant phenolic hydroxyl group permits direct derivatization via etherification or esterification, while the tert-butyl carbamate facilitates mild deprotection under acidic conditions. Its stability, ease of purification, and compatibility with diverse reaction conditions make it ideal for iterative synthesis workflows and API development.
