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 2-ethyl-4-oxopiperidine-1-carboxylate is a bench-stable, moisture-tolerant building block featuring a sterically hindered piperidine core with a ketone at the C4 position. This scaffold integrates readily into complex molecular architectures, enabling efficient access to bioactive heterocycles through selective functionalization at the carbonyl and nitrogen sites.

Application

tert-Butyl 2-ethyl-4-oxopiperidine-1-carboxylate serves as a versatile building block in medicinal chemistry, enabling efficient access to piperidine-based scaffolds. The ketone functionality at C4 supports selective reduction, enolate formation, and nucleophilic addition reactions. The tert-butyl carbamate group provides excellent stability and orthogonal deprotection under mild acidic conditions, facilitating downstream functionalization in multi-step synthesis. Its bench-stable nature and compatibility with diverse reaction conditions make it well-suited for iterative synthesis of bioactive molecules.
