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 cobalt(III) complex features a chiral diamine ligand with bulky di-t-butylsalicylidene groups, delivering high enantioselectivity in catalytic transformations. The p-toluenesulfonate counterion enhances solubility and stability under standard conditions, enabling efficient asymmetric synthesis.

Application

(1S,2S)-(+)-1,2-Cyclohexanediamino-N,N'-bis(3,5-di-t-butylsalicylidene)cobalt(III) p-toluenesulfonate serves as a chiral cobalt(III) complex enabling enantioselective epoxidation and C–H functionalization reactions. Its steric shielding from bulky di-t-butyl groups enhances stereocontrol, while the p-toluenesulfonate counterion ensures solubility and operational stability. The complex exhibits robust bench stability and facilitates high enantiomeric excess in standard oxidation protocols.
