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

tert-Butyl 8-oxa-2,5-diazaspiro[3.5]nonane-2-carboxylate is a spirocyclic scaffold featuring a rigid, electron-rich heterocyclic core with orthogonal functional handles. This bench-stable, moisture-tolerant building block integrates seamlessly into complex molecular architectures, enabling efficient access to bioactive compounds through modular transformations.

Application

tert-Butyl 8-oxa-2,5-diazaspiro[3.5]nonane-2-carboxylate serves as a versatile spirocyclic scaffold for medicinal chemistry and synthetic methodology development. The molecule features a rigid, conformationally constrained core with orthogonal nitrogen and oxygen heteroatoms, enabling selective functionalization. Its tert-butyl carbamate group provides stability and facilitates straightforward deprotection under mild acidic conditions. The spirocyclic architecture supports diverse transformations in C–H activation, cross-coupling, and ring-opening reactions, making it a valuable building block for complex heterocyclic systems and targeted synthesis of bioactive compounds.
