    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

6-Aminopyridine-3-sulfonic acid features a pyridine ring bearing both amino and sulfonic acid groups at meta positions, enabling strong hydrogen bonding and enhanced water solubility. This dual functionality supports its use in dye synthesis, pharmaceutical intermediates, and as a chelating agent in coordination chemistry, where the acidic sulfonate group facilitates metal ion binding under physiological conditions.

Application

6-Aminopyridine-3-sulfonic acid serves as a versatile building block for sulfonated heterocycles, enabling direct incorporation of both amine and sulfonic acid functionalities in medicinal chemistry and materials science. Its dual polar groups enhance solubility and facilitate downstream derivatization via amide coupling or electrophilic substitution. Bench-stable and readily purified by recrystallization, it functions effectively in aqueous and mixed solvent systems for API intermediate synthesis and functional polymer development.
