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+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

This tetrahydrobiindeno[1,2-d]oxazole features a rigid, fused bicyclic scaffold with defined stereochemistry at all chiral centers. The molecule integrates two indeno[1,2-d]oxazole units in a trans-decalin-like arrangement, offering enhanced structural stability and predictable conformational behavior. Its electron-rich heterocyclic system enables efficient coupling in transition metal-catalyzed transformations, while the sterically protected core resists undesired side reactions under standard bench conditions.

Application

(3aR,3'aR,8aS,8'aS)-3a,3'a,8a,8'a-Tetrahydro-8H,8'H-2,2'-biindeno[1,2-d]oxazole serves as a rigid, polycyclic scaffold enabling the construction of complex heterocyclic systems. Its fused indeno-oxazole framework exhibits excellent bench stability and functional group tolerance, facilitating downstream derivatization in medicinal chemistry workflows. The stereochemistry at the bridgehead positions ensures defined conformational behavior, making it valuable for structure-activity studies and targeted synthesis of biologically relevant scaffolds.
