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

This chiral diamine dihydrochloride features a rigid cyclohexane backbone with defined (1R,2R) stereochemistry, enabling precise asymmetric induction. The dimethyl substitution enhances solubility and steric control, while the paired ammonium chloride salts ensure stability and ease of handling in catalytic and synthetic applications.

Application

(1R,2R)-N1,N2-Dimethylcyclohexane-1,2-diamine dihydrochloride serves as a chiral diamine scaffold enabling asymmetric synthesis in transition metal catalysis. Its rigid, enantiopure cyclohexane backbone provides predictable stereocontrol in ligand design, while the N-methyl groups enhance solubility and reduce basicity for improved handling. Functions effectively in Pd- and Cu-catalyzed cross-couplings and C–H functionalizations, offering bench-stable, easily purified intermediates with high reproducibility in multigram-scale applications.
