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.

Description

(S)-tert-Butyl 3-methyl-5-oxopiperidine-1-carboxylate features a chiral piperidine core with a sterically shielded tert-butyl ester and a ketone at the 5-position, enabling direct functionalization at the C3 methyl group. This bench-stable scaffold integrates readily into asymmetric synthesis workflows, delivering high diastereoselectivity in downstream transformations.

Application

(S)-tert-Butyl 3-methyl-5-oxopiperidine-1-carboxylate serves as a versatile chiral building block for the synthesis of piperidine-based pharmaceuticals and bioactive molecules. Its enantioselective configuration enables stereocontrolled functionalization at C3, while the oxo group at C5 facilitates nucleophilic addition and reductive transformations. The tert-butoxycarbonyl (Boc) group provides stable protection under standard conditions, allowing straightforward deprotection and orthogonal handling in multi-step syntheses.
