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.

Type	HazMat Fee
Excepted Quantity	$0.00
FedEx Limited Quantities Ground	$0.00
Hazmat Ground shipping	$50.00+
Inaccessible (Haz class 6.1 or 9), Domestic	$68.00+
Accessible (Haz class 3, 4, 5 or 8), Domestic	$158.00+
Inaccessible (Haz class 6.1 or 9), International	$108.00+

Description

tert-Butyl 7-bromo-1H-indazole-1-carboxylate features a brominated indazole core with a robust tert-butyl ester handle, enabling direct incorporation into cross-coupling reactions. The electron-deficient aromatic system facilitates palladium-catalyzed transformations, while the bench-stable protecting group simplifies purification and handling under standard conditions.

Application

tert-Butyl 7-bromo-1H-indazole-1-carboxylate serves as a versatile building block for the synthesis of brominated indazole derivatives, enabling efficient late-stage functionalization in medicinal chemistry and agrochemical research. The tert-butyl ester group offers excellent bench stability and facile removal under mild acidic conditions, while the bromine substituent provides a reliable handle for palladium-catalyzed cross-coupling reactions, including Suzuki, Stille, and Negishi transformations. Its compatibility with diverse reaction conditions makes it ideal for constructing complex heterocyclic scaffolds in high-purity formats.
