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+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

tert-Butyl 2-oxa-5,8-diazaspiro[3.5]nonane-8-carboxylate features a spirocyclic scaffold integrating oxygen and nitrogen heteroatoms, delivering enhanced stability and solubility in polar organic media. This bench-stable, moisture-tolerant building block enables efficient incorporation into complex molecular architectures via mild deprotection and functionalization protocols.

Application

tert-Butyl 2-oxa-5,8-diazaspiro[3.5]nonane-8-carboxylate serves as a versatile spirocyclic scaffold for medicinal chemistry and synthetic methodology development. The molecule combines a stable tert-butyl ester with a rigid, oxygen-bridged diazaspirocyclic core, enabling selective functionalization at the C8 position. Its bench-stable nature and tolerance to common reaction conditions facilitate downstream transformations, including reductive cleavage, nucleophilic displacement, and transition-metal-catalyzed coupling, making it a practical building block for complex heterocyclic systems.
