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

2-Chloro-3-nitroaniline features a chlorinated aromatic ring paired with adjacent nitro and amino groups, delivering high reactivity in electrophilic substitution. This electron-deficient scaffold enables efficient coupling in pharmaceutical intermediates and agrochemical synthesis under standard conditions.

Application

2-Chloro-3-nitroaniline serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient access to substituted heterocycles via cyclization or cross-coupling reactions. Its ortho-chloro and meta-nitro groups provide complementary reactivity for sequential functionalization, with the nitro group readily reducible to an amine under standard conditions. The compound exhibits good bench stability and facilitates straightforward purification, making it well-suited for multi-step syntheses.
