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

Description

(R)-3-(tert-butyl)-4-(2,3,5,6-tetrahydrobenzo[1,2-b:5,4-b']difuran-8-yl)-2,3-dihydrobenzo[d][1,3]oxaphosphole is a chiral phosphole derivative featuring a sterically shielded tert-butyl group and a fused tetrahydrodibenzodifuran moiety. This configuration enhances stability and facilitates selective coupling in asymmetric synthesis. The oxaphosphole core enables efficient transition metal coordination, supporting its use in catalytic transformations requiring precise stereocontrol.

Application

(R)-3-(tert-butyl)-4-(2,3,5,6-tetrahydrobenzo[1,2-b:5,4-b']difuran-8-yl)-2,3-dihydrobenzo[d][1,3]oxaphosphole serves as a stereochemically defined phosphole building block for the synthesis of chiral phosphorus-containing heterocycles. Its structure features a rigid, fused tetrahydrodibenzodifuran moiety that enhances stability and enables selective functionalization at the phosphole center. The tert-butyl group provides steric protection and facilitates purification, while the dihydrobenzo[d][1,3]oxaphosphole core functions effectively in cross-coupling reactions and transition-metal catalyzed transformations relevant to medicinal chemistry and catalyst development.
