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-1-methyl-1H-benzimidazole is a bench-stable heterocyclic compound featuring a chlorinated benzene ring fused to a methylated imidazole core. This electron-deficient scaffold integrates readily into synthetic routes requiring halogen-directed functionalization or as a building block in pharmaceutical and agrochemical development.

Application

2-Chloro-1-methyl-1H-benzimidazole serves as a versatile building block in medicinal chemistry, enabling efficient construction of biologically active heterocycles. Its chlorinated benzimidazole core exhibits high bench stability and facilitates nucleophilic substitution reactions under mild conditions. The methyl group enhances solubility and provides a handle for further functionalization, making it well-suited for modular synthesis of pharmaceutical intermediates and targeted API scaffolds.
