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+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

tert-Butyl 9-hydroxy-3-azaspiro[5.5]undecane-3-carboxylate features a spirocyclic scaffold with a hydroxyl group at the 9-position and a tert-butyloxycarbonyl-protected amine at the 3-position. This configuration enables selective functionalization in complex molecular architectures, particularly in medicinal chemistry campaigns targeting constrained heterocycles. The molecule exhibits excellent stability under standard handling conditions and facilitates downstream transformations via orthogonal reactivity.

Application

tert-Butyl 9-hydroxy-3-azaspiro[5.5]undecane-3-carboxylate serves as a versatile spirocyclic building block for the synthesis of complex nitrogen-containing scaffolds. The pendant hydroxyl group enables selective derivatization, while the protected amine and ester functionalities offer orthogonal reactivity for late-stage functionalization. Its robust spirocyclic framework provides conformational rigidity, facilitating targeted molecular design in medicinal chemistry applications.
