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+

Description

3-Amino-5-bromo-4-methoxypyridine features a pyridine core functionalized with electron-donating amino and methoxy groups flanking a bromine atom, enabling selective cross-coupling reactions. This scaffold delivers high reactivity in palladium-catalyzed transformations while maintaining bench-stable handling properties under standard conditions.

Application

3-Amino-5-bromo-4-methoxypyridine serves as a versatile building block in medicinal chemistry, enabling efficient construction of functionalized pyridine scaffolds. The amino group facilitates nucleophilic substitution and coupling reactions, while the bromo and methoxy substituents offer orthogonal reactivity for Pd-catalyzed cross-couplings and selective transformations. Its bench-stable nature and compatibility with diverse reaction conditions make it ideal for iterative synthesis of drug candidates and heterocyclic intermediates.
