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

Spiro[2.5]octan-5-one features a rigid, three-dimensional spirocyclic core that imparts exceptional conformational stability. This scaffold integrates a ketone functionality at the bridgehead position, enabling direct participation in stereoselective transformations. The molecule's compact geometry and defined stereochemistry make it an ideal template for asymmetric synthesis and molecular architecture design in medicinal chemistry.

Application

Spiro[2.5]octan-5-one serves as a rigid, bicyclic scaffold enabling the construction of diverse heterocyclic systems and bioactive molecules. Its spirocyclic core provides conformational constraint and enhanced metabolic stability, while the ketone functionality facilitates selective functionalization via nucleophilic addition, enolization, or reductive amination. The compound exhibits excellent bench stability and compatibility with standard synthetic protocols, making it a practical building block for medicinal chemistry and process development.
