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

Methyl 1H-indazole-7-carboxylate features a fused bicyclic indazole core with a strategically positioned ester group at the 7-position, enabling direct functionalization in late-stage synthesis. This electron-deficient heterocycle integrates readily into pharmaceutical scaffolds and serves as a key intermediate for bioactive molecule development.

Application

Methyl 1H-indazole-7-carboxylate serves as a versatile building block for medicinal chemistry and materials science, enabling efficient access to indazole-based scaffolds. Its carboxylate functionality facilitates direct derivatization via ester hydrolysis or coupling reactions, while the indazole core offers robust stability and favorable electronic properties. The methyl ester group enhances solubility and simplifies purification, making it well-suited for high-throughput synthesis and scale-up applications.
