Ferreira, Laura Teófilo [UNESP]; Alarcon, Rafael Turra [UNESP]; Perpétuo, Glauco Lini [UNESP]; Bannach, Gilbert [UNESP]Made available in DSpace on 2018-12-11T17:38:25Z (GMT). No. of bitstreams: 0 Previous issue date: 2018-01-01; This work synthesized and characterized the NOR-RIB 1:1 (mol–mol) cocrystal. During a study of the reagents, Riboflavin (RIB) melted at 304 °C, which is different from the temperature previously reported in the literature (280–290 °C); therefore, this compound was characterized individually. Subsequentl...
