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 5-oxa-2,8-diazaspiro[3.5]nonane-8-carboxylate features a spirocyclic scaffold with oxygen and nitrogen heteroatoms enabling precise stereochemical control. The tert-butyl ester group provides stability and convenient deprotection, while the embedded diazacycle supports integration into complex molecular architectures. This scaffold exhibits favorable solubility and bench-stability under standard conditions.

Application

tert-Butyl 5-oxa-2,8-diazaspiro[3.5]nonane-8-carboxylate serves as a versatile spirocyclic scaffold for medicinal chemistry and catalytic synthesis. The protected amine and ether functionalities enable selective transformations, while the rigid spiro architecture enhances conformational control in target-oriented synthesis. Its bench-stable nature and compatibility with standard coupling reactions facilitate efficient access to complex heterocyclic architectures.
