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

Benzothiazole, a volatile sulfur-containing heterocyclic compound, is one of the key odorants of heated milk. It is also reported to occur as a flavor component of miso, coconut meat and cooked-beef.

Application

(+)-Di-p-toluoyl-D-tartaric acid serves as a highly effective chiral auxiliary in asymmetric synthesis, particularly in enantioselective aldol and Michael additions. Its rigid, well-defined stereochemistry enables high diastereoselectivity, while the p-toluoyl groups enhance solubility and facilitate purification. This compound functions reliably in standard bench-scale transformations, offering excellent reproducibility and operational stability in catalytic asymmetric reactions.
