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

1-(2-Chloro-5-nitrophenyl)ethanone features a chlorinated, electron-deficient aromatic ring paired with a reactive acetyl group. This structure enables direct incorporation into conjugate addition reactions and facilitates efficient coupling in heterocyclic synthesis under standard conditions.

Application

1-(2-Chloro-5-nitrophenyl)ethanone serves as a versatile building block in synthetic organic chemistry, enabling efficient access to substituted heterocycles and pharmaceutical intermediates. Its reactivity profile—characterized by ortho-directing nitro and chloro groups—facilitates electrophilic substitution and palladium-catalyzed coupling reactions. The ketone functionality supports nucleophilic additions and reductions, offering a robust platform for diversification. Bench-stable and readily purified by recrystallization, it is well-suited for scalable synthesis and process development.
