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.

Description

3-Chloro-4-fluorobenzene-1,2-diamine features a dual-heteroatom-substituted aromatic core with ortho-diamino functionality, enabling direct incorporation into azo dyes, pharmaceutical intermediates, and advanced ligands. The electron-withdrawing chlorine and fluorine atoms modulate reactivity and stability under standard conditions.

Application

3-Chloro-4-fluorobenzene-1,2-diamine serves as a key building block for heterocyclic scaffolds in medicinal chemistry, enabling efficient access to substituted quinazolines and benzimidazoles via standard condensation protocols. The ortho-diamine functionality facilitates cyclization under mild conditions, while the complementary chlorine and fluorine substituents offer orthogonal reactivity for downstream functionalization. Bench-stable and readily purified by recrystallization, it functions reliably in multi-step syntheses requiring precise regiocontrol.
