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-Chlorophenylacetic acid features a chlorinated phenyl ring linked to a carboxylic acid group, offering enhanced electronic and steric properties. This structure enables efficient integration into pharmaceutical intermediates and bioactive molecules, particularly where lipophilicity and metabolic stability are critical. The compound exhibits good solubility in organic solvents and maintains stability under standard bench conditions.

Application

3-Chlorophenylacetic acid serves as a versatile building block in medicinal chemistry and agrochemical synthesis, offering a stable arylacetic scaffold with enhanced electrophilicity at the benzylic position. Its functional group tolerance enables reliable derivatization via esterification, amidation, and coupling reactions. The ortho-chloro substituent provides favorable electronic modulation and facilitates downstream transformations such as nucleophilic aromatic substitution or transition-metal-catalyzed cross-couplings. This compound functions effectively in both small-molecule discovery and process-scale applications due to its bench stability and straightforward purification.
