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

This piperidine-based scaffold features a 5-amino-1H-pyrazol-3-yl moiety tethered via a carboxylic acid tert-butyl ester linkage, enabling direct incorporation into bioactive molecule synthesis. The electron-rich pyrazole ring and sterically protected ester group support efficient derivatization under standard conditions.

Application

4-(5-Amino-1H-pyrazol-3-yl)-piperidine-1-carboxylic acid tert-butyl ester serves as a versatile building block for medicinal chemistry campaigns, enabling direct incorporation of the pyrazole scaffold into bioactive molecules. The tert-butyl ester group provides excellent bench stability and facilitates orthogonal deprotection under mild acidic conditions. The pendant amine supports facile derivatization via acylation, alkylation, or coupling reactions, making it ideal for constructing diverse heterocyclic architectures in drug discovery workflows.
