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.

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

Ethyl 4-oxopiperidine-3-carboxylate hydrochloride features a stable, bench-ready piperidine core with a ketone at the C4 position and an ester-functionalized C3. This electrophilic scaffold integrates readily into synthetic sequences requiring nitrogen heterocycles with orthogonal reactivity, particularly in medicinal chemistry and peptide conjugation workflows.

Application

Ethyl 4-oxopiperidine-3-carboxylate hydrochloride serves as a versatile building block in medicinal chemistry, enabling efficient access to piperidine-based scaffolds common in bioactive molecules. Its well-defined reactivity facilitates nucleophilic addition, reductive amination, and cyclization reactions under standard conditions. The hydrochloride salt enhances bench stability and simplifies purification, while the ester and ketone functionalities support diverse downstream transformations. This compound functions reliably in multi-step syntheses requiring functional group compatibility and predictable stereochemical outcomes.
