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

This triazole-functionalized acetic acid derivative integrates a 1,2,3-triazole ring directly at the alpha position, enabling robust bioorthogonal conjugation. The stable, bench-stable scaffold facilitates efficient coupling in peptide and small-molecule labeling workflows without requiring transition metals or harsh conditions.

Application

2-(1H-1,2,3-Triazol-1-yl)acetic acid serves as a versatile building block in click chemistry and medicinal chemistry applications. The triazole moiety provides excellent metabolic stability and hydrogen-bonding capacity, while the carboxylic acid group enables straightforward conjugation via amide bond formation. This compound exhibits good bench stability, facilitates efficient purification by crystallization, and functions reliably in standard coupling reactions with amines, alcohols, and nucleophiles under mild conditions.
