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+
Accessible (Haz class 3, 4, 5 or 8), International	$238.00+

Description

This chiral phosphole features a sterically shielded tert-butyl group and an electron-rich aryl moiety with dual methoxy and isopropyl substituents, enabling robust coordination in asymmetric catalysis. Its bench-stable, moisture-tolerant structure simplifies handling in air-sensitive transformations.

Application

(R)-3-(tert-Butyl)-4-(3,5-diisopropyl-2,6-dimethoxyphenyl)-2,3-dihydrobenzo[d][1,3]oxaphosphole serves as a sterically encumbered, bench-stable phosphole scaffold enabling efficient transition-metal-catalyzed cross-coupling reactions. Its ortho-dimethoxy substitution enhances electronic modulation and solubility, while the chiral tertiary phosphorus center provides stereochemical control in asymmetric synthesis. Functions effectively in Pd-catalyzed coupling protocols and acts as a versatile building block for bioactive heterocyclic systems.
