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

Description

This hydrochloride salt features a 2-aminothiazol-4-yl moiety linked to an acetic acid side chain, delivering enhanced solubility and stability under standard conditions. The scaffold integrates readily into peptide-based conjugates and bioactive molecules, serving as a robust building block for medicinal chemistry campaigns targeting kinase inhibition and antimicrobial agents.

Application

2-(2-Aminothiazol-4-yl)acetic acid hydrochloride serves as a key building block for thiazole-containing pharmaceuticals, enabling efficient access to bioactive scaffolds through standard amide coupling and electrophilic substitution reactions. Its amine functionality offers high reactivity in peptide synthesis and derivatization workflows, while the hydrochloride salt enhances solubility and bench stability. Functions reliably in diverse synthetic contexts requiring nitrogen heterocycles with orthogonal functional handles.
