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-Amino-4,5-dichlorophenol features a phenolic hydroxyl group flanked by two chlorine substituents and an amino functionality at the para position relative to the OH. This combination imparts enhanced electrophilicity and polarity, enabling efficient coupling in nucleophilic substitution reactions. The molecule exhibits bench-stable behavior under standard conditions and integrates readily into heterocyclic syntheses and agrochemical intermediates.

Application

2-Amino-4,5-dichlorophenol serves as a versatile building block in medicinal chemistry and agrochemical synthesis, enabling efficient construction of substituted heterocycles via electrophilic substitution and coupling reactions. Its dual functionality—phenolic hydroxyl and primary amine—facilitates orthogonal derivatization, while the dichloro substitution pattern supports regioselective functionalization. The compound exhibits good bench stability and is compatible with standard purification protocols, making it well-suited for scalable synthesis workflows.
