Experimental Properties:Visible or ultraviolet radiation of alkaline solutions causes the formation of lumiflavine ... whereas irradiation of acid or neutral solutions gives rise to the production of lumichrome ... togther with varying amounts of lumiflavine|Sensitive to alkalies; stable to mineral acids in the dark|In solution, riboflavin has an intense greenish-yellow flourescence|In alkaline solution it is readily soluble but quite unstable to heat and to light forming lumiflavin, a fluorescent degradation product. Riboflavin is nore stable to heat in acid solution, particularly from pH 1.0 to 6.5 but upon irradiation forms lumichrome. Riboflavin is readily adsorbed from acid or neutral solution on such agents as frankonite, fuller's earth, and certain zeolites, and eluted with acetone or pyridine solutions.|For more Other Experimental Properties (Complete) data for Riboflavin (6 total), please visit the HSDB record page.
