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

tert-Butyl 6-formyl-2-azaspiro[3.3]heptane-2-carboxylate features a spirocyclic scaffold with a formyl group at the C6 position and a tert-butyl ester at C2, offering a sterically shielded, bench-stable platform for late-stage functionalization in complex molecule synthesis.

Application

tert-Butyl 6-formyl-2-azaspiro[3.3]heptane-2-carboxylate serves as a versatile spirocyclic building block for the synthesis of nitrogen-containing heterocycles. The formyl group enables efficient functionalization via imine formation, reductive amination, and Mannich reactions, while the tert-butyl ester offers stability and convenient deprotection under mild acidic conditions. Its rigid spirocyclic framework provides defined stereochemistry and is compatible with diverse transformations in medicinal chemistry and process development workflows.
