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

This spirocyclic heterocycle features a rigid, three-dimensional scaffold with embedded nitrogen and oxygen atoms, delivering enhanced metabolic stability and improved solubility. The hydrochloride salt form ensures excellent crystallinity and handling ease, enabling efficient integration into medicinal chemistry campaigns targeting CNS disorders and kinase inhibition pathways.

Application

2-Oxa-9-azaspiro[5.5]undecane hydrochloride serves as a stable, crystalline spirocyclic scaffold enabling efficient access to nitrogen-containing heterocycles via standard functionalization protocols. Its orthogonally protected amine and ether functionalities facilitate selective derivatization, supporting applications in medicinal chemistry libraries and solid-phase synthesis. The hydrochloride salt enhances solubility and handling, while the rigid spiro structure provides conformational constraint beneficial for target engagement studies.
