Thirdly, The first melting point was described in the early 1940s followed by several examples in later years (Section B). More detailed analytical were published in 1992 and included thermal investigations into the nature of polymorphism, 20NMR21 and crystal structure analysis.
Moreover, 22 The first comprehensive characterization of 4-FA and related isomers and derivatives was reported in 2005. 23 Presumptive test results for 4-FA using the RAL color scheme were as follows. Marquis: RAL 9003 at 0 min and RAL 2012 at 5 min; Mecke: RAL 9003 at 0 min and RAL 1016 at 5 min; Mandelin.
