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.

Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+

Description

This (S)-configured oxaphosphole features a sterically shielded tert-butyl group and a electron-rich aryl substituent bearing two methoxy and two methyl groups. The dihydrobenzo[d][1,3]oxaphosphole core provides a stable, moisture-tolerant phosphorus center suitable for asymmetric synthesis and ligand development in catalytic transformations.

Application

(S)-3-(tert-butyl)-4-(2,6-dimethoxy-3,5-dimethylphenyl)-2,3-dihydrobenzo[d][1,3]oxaphosphole serves as a chiral, bench-stable phosphine ligand that enables efficient transition-metal-catalyzed cross-coupling reactions. Its sterically encumbered tert-butyl group and electron-rich aryl substituents enhance catalyst stability and reactivity in palladium-catalyzed couplings. The dihydrobenzo[d][1,3]oxaphosphole core provides robust coordination to metal centers while maintaining ease of purification and compatibility with diverse functional groups.
