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 8-oxo-5-azaspiro[3.5]nonane-5-carboxylate features a rigid spirocyclic scaffold with a ketone at C8 and a tertiary amine at the bridgehead, enabling precise stereocontrol in asymmetric synthesis. The tert-butyl ester group provides stability and facilitates subsequent deprotection under mild acidic conditions. This compound serves as a key building block for nitrogen-containing polycycles in medicinal chemistry.

Application

tert-Butyl 8-oxo-5-azaspiro[3.5]nonane-5-carboxylate serves as a versatile spirocyclic building block for medicinal chemistry and natural product synthesis, enabling efficient access to nitrogen-containing heterocycles. The molecule combines a stable tert-butyl ester with a ketone-functionalized azaspirocycle, offering orthogonal reactivity for selective transformations. Its bench-stable nature and compatibility with standard coupling and reduction protocols facilitate streamlined synthetic workflows in API development.
