Lemmerer, Andreas published the artcileThe 2-Chloro-4-nitrobenzoic acid as a coformer with pharmaceutical cocrystals and molecular salts, SDS of cas: 1453-82-3, the publication is Acta Crystallographica, Section C: Structural Chemistry (2020), 76(8), 746-752, database is CAplus and MEDLINE.
A series of five binary complexes, i.e. three cocrystals and two mol. salts, using 2-chloro-4-nitrobenzoic acid as a coformer have been produced with five commonly available compounds, some of pharmaceutical relevance, namely, 2-chloro-4-nitrobenzoic acid-isonicotinamide (1/1), C7H4ClNO4·C6H6N2O, 2-chloro-4-nitrobenzoic acid-3,3-diethylpyridine-2,4(1H,3H)-dione (2/1), 2C7H4ClNO4·C9H13NO2, 2-chloro-4-nitrobenzoic acid-pyrrolidin-2-one (1/1), C7H4ClNO4·C4H7NO, 2-carboxypiperidinium 2-chloro-4-nitrobenzoate, C6H12NO2-·C7H3ClNO4-, and (2-hydroxyethyl)ammonium 2-chloro-4-nitrobenzoate, C2H8NO+·C7H3ClNO4-. The coformer falls under the classification of a generally regarded as safe compound All five complexes make use of a number of different heteromeric hydrogen-bonded interactions. Intermol. potentials were evaluated using the CSD-Materials module.
