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

3,4-Dichloro-1,2,5-thiadiazole has been employed:as guest molecule to investigate solid-state 13C NMR spectra of inclusion compounds of 2,6-dimethyl-bicyclo[3.3.1]nonane-exo-2-exo-6-diol with small organic moleculesin preparation of [1,2,5]thiadiazol-3-yl-piperazine compounds

Application

3,4-Dichloro-1,2,5-thiadiazole serves as a versatile electrophilic building block in synthetic organic chemistry, enabling the efficient construction of nitrogen- and sulfur-containing heterocycles. Its dichloro substitution pattern facilitates regioselective functionalization via nucleophilic displacement, offering reliable access to substituted thiadiazoles under mild conditions. The compound exhibits good bench stability and compatibility with common reaction solvents, making it a practical reagent for medicinal chemistry and process development workflows.
