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.

Description

(S,S)-iPr-Bisbox is a chiral bis(oxazoline) ligand featuring isopropyl substituents that enhances steric bulk and enantioselectivity in transition metal catalysis. This bench-stable, moisture-tolerant scaffold integrates readily into asymmetric synthesis workflows, enabling high diastereo- and enantiocontrol in reactions such as cycloadditions and conjugate additions.

Application

(S,S)-iPr-Bisbox serves as a robust chiral ligand in asymmetric transition-metal catalysis, enabling high enantioselectivity in reactions such as conjugate additions and C–C bond formations. Its isopropyl-substituted bis(oxazoline) framework provides enhanced stereocontrol and bench stability, facilitating reproducible outcomes in synthetic workflows.
