WebContext. It is well known that hydrogen cyanide and formamide can universally be considered as key molecules in prebiotic synthesis. Despite the fact that formamide has been detected in interplanetary and interstellar environments, other prebiotic Webthe use of DSC for measuring boiling points or generating vapor pressure curves. This preboiling vaporization tends to broaden boiling endotherms, may exhaust the specimen before the actual boiling point, or can self-pressurize a sealed specimen. Recent efforts to increase the utility of DSC for studying volatile specimens have shown that a ...
