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

tert-Butyl (2R,4R)-4-amino-2-methylpiperidine-1-carboxylate is a stereochemically defined piperidine derivative featuring a bench-stable tert-butyl carbamate protecting group. This configuration enables efficient incorporation into complex molecular architectures, particularly in the synthesis of bioactive heterocycles and peptidomimetics. The amino functionality supports direct derivatization, while the methyl substituent enhances steric control during cyclization steps.

Application

tert-Butyl (2R,4R)-4-amino-2-methylpiperidine-1-carboxylate serves as a stereochemically defined building block for the synthesis of bioactive piperidine derivatives. The protected amine and chiral methylpiperidine core enable direct incorporation into medicinal chemistry campaigns, facilitating efficient access to constrained scaffolds via standard coupling, alkylation, or reductive amination protocols. Bench-stable and compatible with diverse functional groups, it functions as a versatile intermediate in API development workflows requiring precise stereocontrol.
