    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.

Description

tert-Butyl 2-oxa-7-azaspiro[3.5]nonane-7-carboxylate is a sterically shielded spirocyclic heterocycle featuring a stable oxazepine core and a bench-stable tert-butyl ester. This scaffold integrates a nitrogen atom at the spiro junction and an oxygen bridge, enabling precise control over conformational rigidity and solubility. The protected carboxylate group facilitates downstream derivatization in synthetic sequences involving macrocyclization or medicinal chemistry optimization.

Application

tert-Butyl 2-oxa-7-azaspiro[3.5]nonane-7-carboxylate serves as a versatile spirocyclic scaffold for medicinal chemistry, enabling the construction of constrained heterocycles with defined stereochemistry. The protected amine and ester functionalities offer orthogonal reactivity, facilitating downstream transformations such as hydrogenolysis, hydrolysis, or coupling reactions. Its bench-stable nature and compatibility with standard synthetic protocols make it well-suited for iterative synthesis and library generation.
