4- Chloro-2-methylbenzoic acid

As mentioned above, Caira et al. implicated the stability of an ingoing cocrystallisation component as a factor in the preferential formation of a sulfadimidine cocrystal [36]. A year later,in a detailed structural analysis of three anthracene 16 cocrystals, Pedireddi et al. concluded that the ability of potential constituents to satisfy a network of hydrogen bonds dictated solid-state cocrystal formation [43]. Cocrystallisations of anthracene 16 with 4-chloro-3,5-dini-trobenzoic acid 17,3,5-dinitro-4-methylbenzoic acid 18 and 3,5-dinitrobenzoic...
