    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-Bromo-2-fluorophenyl)hydrazine hydrochloride features a bromo-fluoro-substituted phenyl ring paired with a hydrazine moiety, enabling direct coupling in heterocyclic synthesis. The hydrochloride salt enhances solubility and stability under standard conditions, facilitating use in transition-metal-catalyzed transformations and medicinal chemistry applications.

Application

(4-Bromo-2-fluorophenyl)hydrazine hydrochloride serves as a versatile building block for constructing bioactive heterocycles, particularly in the synthesis of triazoles and imidazoles via cyclization reactions. Its well-documented stability under standard handling conditions enables reliable use in multi-step sequences, with the bromo and fluoro substituents offering orthogonal reactivity for subsequent cross-coupling or functional group manipulation in medicinal chemistry workflows.
