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

(-)-O,O-Di-p-toluoyl-L-tartaric acid is a O,O-diacyl tartaric acid derivative that can be prepared by the resolution of its racemate in the presence of cinchonine.(-)-O,O-Di-p-toluoyl-L-tartaric acid may be used as a chiral resolving agent for the resolution of the racemic bases to isolate the (-)-enantiomeric forms.

Application

(-)-Di-p-toluoyl-L-tartaric Acid serves as a highly effective chiral auxiliary in asymmetric synthesis, enabling stereoselective transformations through well-documented enantiocontrol. Its robust diester functionality facilitates conjugate additions, alkylations, and Michael reactions with high diastereoselectivity. The p-tolyl groups enhance crystallinity and ease of purification, while the stable chiral backbone allows for reliable handling and scalability in benchtop applications.
