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.

Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

tert-Butyl 7-hydroxy-2-azaspiro[4.4]nonane-2-carboxylate features a rigid spirocyclic scaffold with a hydroxyl group at the 7-position and a tert-butyloxycarbonyl-protected amine at the 2-position. This configuration enables direct functionalization at the hydroxyl site while maintaining stability under standard conditions, facilitating efficient access to complex nitrogen-containing architectures in medicinal chemistry and natural product synthesis.

Application

tert-Butyl 7-hydroxy-2-azaspiro[4.4]nonane-2-carboxylate serves as a versatile spirocyclic scaffold for medicinal chemistry applications, offering a rigid, three-dimensional core with orthogonal functional handles. The hydroxyl group enables direct derivatization via esterification or oxidation to ketone, while the tert-butyl carbamate protects the secondary amine under standard reaction conditions. Its bench-stable nature and compatibility with diverse coupling and cyclization protocols facilitate efficient access to complex heterocyclic architectures in API development.
