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 phospholane incorporates a sterically shielded tert-butyl group and a diphenylpyrrole scaffold, delivering enhanced stability and defined stereochemical control. The electron-rich pyrrole moiety pairs with the phosphorus heterocycle to enable selective coordination in asymmetric catalysis, particularly in transition-metal-mediated transformations requiring robust ligand frameworks under standard bench conditions.

Application

(S)-1-(3-(tert-butyl)-2,3-dihydrobenzo[d][1,3]oxaphosphol-4-yl)-2,5-diphenyl-1H-pyrrole serves as a versatile chiral phosphorus-containing building block for the synthesis of functionalized heterocycles. Its stability under standard reaction conditions and compatibility with diverse functional groups facilitate efficient access to complex scaffolds in medicinal chemistry. The tert-butyl substituent enhances steric protection and solubility, while the pyrrole core enables further derivatization via electrophilic substitution or transition-metal-catalyzed coupling. This compound functions as a key intermediate in asymmetric synthesis and catalytic systems requiring defined stereochemistry and phosphorus functionality.
