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

Description

This tetrahydroindeno[1,2-d]oxazolone features a rigid, fused bicyclic scaffold with a lactam functionality, offering enhanced stability and defined stereochemistry. The 3aS,8aR configuration enables predictable reactivity in asymmetric synthesis, where the carbonyl group serves as a key handle for nucleophilic transformations. Its bench-stable nature supports reliable use in multi-step synthetic sequences.

Application

(3aS,8aR)-3,3a,8,8a-Tetrahydro-2H-indeno[1,2-d]oxazol-2-one serves as a versatile chiral building block for the synthesis of bioactive heterocycles. Its rigid fused ring system provides defined stereochemistry and enhances metabolic stability in medicinal chemistry applications. The oxazolone functionality enables selective nucleophilic additions and participates in transition-metal-catalyzed coupling reactions. Bench-stable and readily purified by flash chromatography, it facilitates efficient access to complex scaffolds in API development workflows.
