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

2,5-Dichloropyridin-4-amine features a pyridine core bearing two chlorine substituents at the 2 and 5 positions and an amino group at the 4-position. This electron-deficient heterocycle serves as a key building block in medicinal chemistry, enabling direct coupling reactions through its nucleophilic amine and halogenation sites. The molecule exhibits enhanced stability under standard conditions and facilitates efficient diversification in target-oriented synthesis.

Application

2,5-Dichloropyridin-4-amine serves as a versatile building block in medicinal chemistry, enabling direct functionalization at the 4-position via nucleophilic substitution. Its dichloro substitution pattern provides orthogonal reactivity for sequential coupling processes, while the amine group facilitates amidation, sulfonamide formation, and transition-metal-catalyzed cross-couplings. The compound exhibits excellent bench stability and is readily purified by recrystallization, making it ideal for scalable synthesis of heterocyclic scaffolds found in agrochemicals and pharmaceuticals.
