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

Methyl 4-bromo-5-chloropicolinate features a sterically accessible pyridine core bearing strategically positioned bromo and chloro substituents, enabling selective cross-coupling reactions. This bench-stable derivative integrates readily into synthetic sequences requiring halogen-directed functionalization, offering enhanced reactivity control in transition metal-catalyzed transformations.

Application

Methyl 4-bromo-5-chloropicolinate serves as a versatile building block in synthetic organic chemistry, enabling regioselective cross-coupling reactions via its complementary halogenation pattern. The bromo group facilitates palladium-catalyzed coupling with boronic acids, while the chloro substituent offers orthogonal reactivity for subsequent functionalization. Its bench-stable methyl ester functionality simplifies purification and supports downstream transformations into bioactive heterocycles or pharmaceutical intermediates.
