Building Blocks

Stability Moisture Sensitive
Applications Norcantharidin is a potential antitumor agent.

Stability Hygroscopic
Applications Cyanuric Chloride is extensively used in the preparation of the triazine-class pesticides and herbicides. Cyanuric chloride is also used as a precursor to dyes and crosslinking agents due to the reactive chlorine atoms towards nucleophilic substitution reactions. Cyanuric chloride derivatives possess a large spectrum of activities as antibacterial and anticancer agents.

Applications One of the alkyl ethers with tert-Bu groups in their molecules which showed very poor biodegradability, tert-Bu Me ether (MTBE)  [1634-04-4] had no effect on the biodegradability of gasoline blended with it. Studies on the biodegradation of several alkyl ethers were carried out by measuring the O uptake rate in the presence of standard activated sludge as a source of microorganisms.
