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

3-Chloro-2-methoxypyridine-5-boronic acid features a pyridine scaffold bearing a boronic acid group at the 5-position and complementary substituents at the 3-chloro and 2-methoxy sites. This configuration enables direct incorporation into Suzuki-Miyaura cross-coupling reactions under standard conditions, delivering functionalized heterocycles with high chemoselectivity. The methoxy group enhances solubility in polar solvents, while the chloropyridine moiety provides a handle for further derivatization. This compound serves as a key intermediate in the synthesis of bioactive molecules and advanced materials.

Application

3-Chloro-2-methoxypyridine-5-boronic acid serves as a versatile building block in palladium-catalyzed cross-coupling reactions, enabling efficient construction of biaryl and heteroaryl architectures. The boronic acid functionality offers excellent bench stability and compatibility with diverse reaction conditions, while the chloro and methoxy groups provide orthogonal reactivity for sequential functionalization. This compound facilitates rapid access to complex pyridine-based scaffolds relevant to medicinal chemistry and materials science.
