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

tert-Butyl 4-(4-aminophenoxy)piperidine-1-carboxylate features a piperidine core linked to a para-aminophenoxy moiety, enabling direct incorporation into bioactive scaffolds. The tert-butyl ester group provides stability and facilitates deprotection under mild acidic conditions. This compound serves as a key intermediate in the synthesis of kinase inhibitors and CNS-targeted therapeutics.

Application

tert-Butyl 4-(4-aminophenoxy)piperidine-1-carboxylate serves as a versatile building block for the synthesis of bioactive heterocycles, enabling efficient construction of piperidine-based scaffolds through standard amine functionalization. The protected amine and phenoxy ether functionalities exhibit excellent bench stability and compatibility with diverse coupling reactions. Its ease of purification and predictable reactivity make it well-suited for medicinal chemistry campaigns requiring rapid access to analogues.
