Application

Etidronic acid (HEBP) can be employed as a catalyst for the synthesis of:
  • 5-Nitro-3,4-dihydropyrimidin-2(1H)-ones through the reaction between 1-(2-hydroxyphenyl)-2-nitroethanone, aryl aldehydes and urea via one-pot cyclo condensation reaction.
  • Thiiranes from epoxides and ammonium thiocyanate.

Endodontic infections are often interkingdom biofilms, though current clinical management rarely considers this phenomenon. This study aimed to evaluate new and standard endodontic antimicrobial regimens against simple and complex Candida albicans and Enterococcus faecalis mono- and dual-species biofilms. C. albicans

The effects of phosphonates, the heavily-used antiscalants in reverse osmosis systems, on microalgae are controversial, although they are harmless to most aquatic organisms. Herein, we assessed the inhibitory effects of etidronic acid (HEDP) and diethylenetriamine penta(methylene phosphonic acid) (DTPMP) on
