    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

tert-Butyl N-(3-chloro-1H-pyrazol-4-yl)carbamate features a bench-stable carbamate protecting group that enables selective functionalization at the pyrazole nitrogen. The electron-deficient pyrazole ring enhances reactivity in cross-coupling and nucleophilic substitution processes, while the tert-butyl moiety ensures excellent solubility and stability under standard conditions.

Application

tert-Butyl N-(3-chloro-1H-pyrazol-4-yl)carbamate serves as a versatile pyrazole-based building block in medicinal chemistry, enabling direct functionalization at the 4-position via standard cross-coupling reactions. The carbamate group provides excellent bench stability and facilitates easy deprotection under mild acidic conditions. Its compatibility with palladium-catalyzed transformations and tolerance for diverse reaction partners make it a practical choice for constructing bioactive heterocyclic scaffolds.
