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

Description

L-(+)-Valinol reacts with aldehydes and nitriles to form imines and oxazolines, respectively, for asymmetric synthesis. It is also used for preparation of 4-isopropyloxazolidinones, employed in stereocontrolled aldol and alkylation reactions, synthesis of chiral 2-thiazolidinethiones for aldol reactions, asymmetric alkylation of condensation product with keto acids, asymmetric reactions of its amidines and imines and oxidation of N-protected derivative to the aldehyde.

Application

3,4-Dimethylphenylboronic acid serves as a versatile building block in Suzuki-Miyaura cross-coupling reactions, enabling efficient C–C bond formation under mild conditions. Its ortho-dimethyl substitution enhances stability and modulates reactivity, while the boronic acid group offers excellent functional group tolerance and ease of purification. Ideal for constructing substituted biaryl scaffolds in medicinal chemistry and materials science applications.
