Aldehydes, halogenation

Bacterial spores are the most resistant of all microbial forms to chemical treatment. The majority of antimicrobial agents have no useful sporicidal action, with the exception of the aldehydes, halogens and peroxygen compounds. Such chemicals are sometimes used as an alternative to physical methods for sterilization ofheat sensitive equipment. In these circumstances, correct usage of the agent is of paramount importance since safety margins are lower in comparison with physical methods of sterilization (Chapter 20). 

Halogenated selenophene-2-aldehydes may be obtained either from selenophene-2-aldehyde halogenated (chlorinated or brominated) by the respective V-halosuccinimide72 or by formylation of the 2-halo-selenophenes.72,73...

A negative effect on the vitality of microorganisms is generally referred as antimicrobial action. The activity which affects bacteria is known as antibacterial and that which affects fungi as antimycotic. Oxidising agents such as aldehydes, halogens and peroxy...
