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

4-Chloro-N-hydroxybenzimidamide delivers a reactive hydroxylamine moiety paired with a chlorinated benzimidazole scaffold, enabling efficient coupling in bioconjugation and medicinal chemistry applications. This bench-stable compound features enhanced solubility and selective reactivity under standard conditions.

Application

4-Chloro-N-hydroxybenzimidamide serves as a versatile building block for heterocyclic synthesis, enabling efficient access to bioactive benzimidazole derivatives. Its N–OH functionality facilitates direct amidation and coupling reactions, while the chloro substituent supports palladium-catalyzed cross-coupling transformations. The compound exhibits good bench stability and is readily purified by recrystallization, making it suitable for iterative medicinal chemistry campaigns and API intermediate development.
