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 7-formyl-2-azaspiro[3.5]nonane-2-carboxylate features a spirocyclic scaffold with a formyl group at the C7 position and a tert-butyl ester at C2, enabling direct functionalization. The electron-deficient aldehyde facilitates nucleophilic additions and condensation reactions. This bench-stable intermediate integrates efficiently into complex heterocyclic syntheses, particularly in medicinal chemistry campaigns targeting constrained nitrogen-containing frameworks.

Application

tert-Butyl 7-formyl-2-azaspiro[3.5]nonane-2-carboxylate serves as a versatile spirocyclic scaffold for medicinal chemistry campaigns, enabling direct access to complex nitrogen-containing heterocycles. The pendant aldehyde group facilitates efficient imine formation, reductive amination, and cyclization reactions under mild conditions. Its tert-butyl ester offers excellent bench stability and simplifies purification, while the constrained spiro architecture provides defined stereochemical control in downstream transformations.
