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+

Description

This chiral piperidine derivative features a tert-butyl group at the nitrogen and a methyl substituent at the 2-position, delivering enhanced steric protection and stability. The (R)-configured scaffold integrates seamlessly into asymmetric synthesis workflows, enabling efficient access to complex alkaloid frameworks and bioactive molecules under standard conditions.

Application

1-(tert-Butyl) 2-methyl (R)-4-oxopiperidine-1,2-dicarboxylate serves as a versatile chiral building block in medicinal chemistry, enabling efficient access to piperidine-containing scaffolds. Its tert-butyl ester group offers excellent bench stability and ease of removal under mild acidic conditions, while the methyl and oxo substituents provide defined stereochemistry and functional handles for downstream derivatization. The molecule facilitates stereoselective transformations in API synthesis and is compatible with standard coupling and reduction protocols.
