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
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+

Description

This boronic acid features a chloro-substituted aromatic ring with a formyl group positioned ortho to the boronate moiety. The electrophilic formyl function enables direct coupling in Suzuki-Miyaura reactions, while the chlorine atom serves as a latent handle for downstream functionalization. Bench-stable and moisture-tolerant, it streamlines access to complex heterocycles and bioactive scaffolds in medicinal chemistry workflows.

Application

(2-Chloro-5-formylphenyl)boronic acid serves as a versatile building block in Suzuki-Miyaura coupling reactions, enabling the efficient construction of biaryl scaffolds under mild conditions. The formyl group provides orthogonal reactivity for downstream functionalization via oxime or hydrazone formation, while the boronic acid moiety offers excellent bench stability and compatibility with diverse reaction partners. Its dual functionality facilitates rapid access to complex molecular architectures common in medicinal chemistry and materials science.
