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-1,3,4-thiadiazole is a heterocyclic compound featuring a chlorine atom at the 2-position, conferring enhanced electrophilicity and reactivity. This electron-deficient scaffold integrates readily into synthetic pathways requiring polarizable ring systems. The molecule exhibits bench-stable handling characteristics and serves as a key building block in medicinal chemistry and agrochemical development.

Application

2-Chloro-1,3,4-thiadiazole serves as a versatile electrophilic building block in heterocyclic synthesis, enabling efficient functionalization at the 2-position via nucleophilic substitution. Its stability under standard reaction conditions and compatibility with diverse nucleophiles facilitate access to substituted thiadiazoles used in medicinal chemistry and agrochemical scaffolds. The molecule functions as a key intermediate in the construction of bioactive heterocycles and exhibits favorable handling properties for routine bench-scale applications.
