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-Chloro-6,7-dimethoxyquinoline-3-carbaldehyde features a quinoline core functionalized with chlorine and two methoxy groups at positions 2, 6, and 7, respectively, and an aldehyde group at C3. This electron-deficient scaffold integrates readily into synthetic routes for bioactive molecules, leveraging its polar aldehyde handle and steric profile for selective coupling reactions under standard conditions.

Application

2-Chloro-6,7-dimethoxyquinoline-3-carbaldehyde serves as a versatile building block in medicinal chemistry, enabling efficient access to quinoline-based scaffolds. Its aldehyde functionality facilitates reductive amination, Ugi-type condensations, and Suzuki-Miyaura coupling reactions. The ortho-chloro and dimethoxy substituents provide enhanced stability and favorable electronic properties for downstream functionalization, while the molecule exhibits excellent bench stability and ease of purification—making it well-suited for high-throughput synthesis and process development workflows.
