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

Methyl 2-chloro-1H-benzo[d]imidazole-5-carboxylate is a bench-stable, moisture-tolerant heterocyclic building block featuring a chlorinated imidazole core and an ester-functionalized position. This compound integrates readily into synthetic sequences requiring electron-deficient aromatic scaffolds, enabling efficient access to bioactive derivatives in medicinal chemistry and materials science applications.

Application

Methyl 2-chloro-1H-benzo[d]imidazole-5-carboxylate serves as a versatile building block for the synthesis of biologically active heterocycles. The chloro group at the 2-position enables palladium-catalyzed cross-coupling reactions, while the ester functionality supports further derivatization via hydrolysis or reduction. Its bench-stable nature and compatibility with standard reaction conditions facilitate efficient access to substituted benzimidazoles relevant in medicinal chemistry and agrochemical research.
