    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

(2,3-Dichlorophenyl)hydrazine hydrochloride delivers a readily accessible hydrazine handle for constructing heterocyclic scaffolds in medicinal chemistry. The dichlorophenyl moiety imparts enhanced lipophilicity and metabolic stability, while the hydrochloride salt form ensures improved solubility and handling under standard conditions. This compound serves as a key intermediate in the synthesis of bioactive nitrogen-containing compounds.

Application

(2,3-Dichlorophenyl)hydrazine hydrochloride serves as a reliable building block for heterocyclic synthesis, particularly in the construction of pyrazole and triazole scaffolds. Its stability under ambient conditions and compatibility with standard coupling protocols enable efficient access to functionalized aromatic hydrazones. The molecule facilitates regioselective cyclizations and exhibits predictable reactivity in condensation reactions, making it a practical choice for medicinal chemistry campaigns requiring chlorinated aryl motifs.
