    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 diester features two (2-methylbenzoyl) ester groups at the 2 and 3 positions of a succinic acid backbone, enabling selective derivatization in asymmetric synthesis. The ortho-methyl substitution enhances steric control during enantioselective transformations.

Application

(2S,3S)-2,3-Bis((2-methylbenzoyl)oxy)succinic acid serves as a chiral auxiliary in asymmetric synthesis, enabling stereocontrolled functionalization through its rigid, well-defined stereocenters. The molecule’s benzoate ester groups provide excellent bench stability and facilitate straightforward purification via crystallization. It functions effectively in diastereoselective transformations, particularly in enantioselective acylations and cyclizations, offering predictable stereochemical outcomes in the construction of complex molecular architectures.
