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[2.2]pentane-1-carboxylic acid delivers a rigid, three-dimensional scaffold with enhanced metabolic stability and improved solubility profiles. The spirocyclic core resists conformational flexibility, while the carboxylic acid group enables direct conjugation or derivatization under standard conditions. This structure facilitates efficient incorporation into bioactive molecules requiring steric shielding and controlled polarity.

Application

Spiro[2.2]pentane-1-carboxylic acid serves as a rigid, bicyclic building block for medicinal chemistry and materials science, offering enhanced metabolic stability and conformational constraint. Its carboxylic acid functionality enables direct derivatization via standard coupling reactions, while the spirocyclic core imparts excellent bench stability and orthogonal reactivity in multi-step syntheses.
