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

(R)-3-(tert-Butyl)-4-(2,6-diphenoxyphenyl)-2,3-dihydrobenzo[d][1,3]oxaphosphole is a chiral phosphole derivative featuring a sterically shielded tert-butyl group and electron-rich diphenoxy substitution. This configuration enhances stability and directs stereoselective transformations in asymmetric catalysis. The fused oxaphosphole core provides a rigid, electron-deficient platform for metal coordination, enabling efficient ligand integration in transition-metal-catalyzed processes.

Application

(R)-3-(tert-Butyl)-4-(2,6-diphenoxyphenyl)-2,3-dihydrobenzo[d][1,3]oxaphosphole serves as a stereochemically defined phosphole scaffold with enhanced bench stability and functional group tolerance. It enables efficient access to chiral phosphorus-containing building blocks via P–C bond formation, facilitates transition-metal-catalyzed coupling reactions, and functions as a versatile intermediate in the synthesis of phosphine ligands and bioactive heterocyclic systems.
