Abstract. A structural analysis of over 80 salts and cocrystals synthesized from equimolar amounts of carboxylic acids and N-heterocycles demonstrates that salt formation as a result of proton transfer from the acid to the base frequently (11/24; 45%) results in a lattice with an unpredictable chemical (solvate) or stoichiometric composition.

As a state-of-the-art example, Tomislav et al reported the monitoring of the continuous production of cocrystal polymorphs from a twin-screw extruder granulator using Raman spectroscopy. 32 This method enables the discrimination of cocrystal polymorphs during continuous manufacturing by the difference between 50 and 170 cm −1 in Raman …

TTC cocrystal single crystal appears dark black in color with a me-tallic luster and displays an impressive difference from its compo-nents (fig. S2), which is agreed with the single-crystal data (a = 8.427 Å, b = 8.938 Å, c = 7.932 Å, α = 93.36°, β = 109.60°, and γ = 72.22°) (table S1). These results are powerful for confirming the ...

The present study deals with the application of mechanochemical approach for the preparation of drug-drug multicomponent solid forms of three poorly soluble antihypertensive drugs (telmisartan, irbesartan and hydrochlorothiazide) using atenolol as a coformer. The resultant solid forms comprise of cocrystal (telmisartan-atenolol), …

The results showed that Ila/Xyl cocrystal reached 55% within 15 min and within 45 min, while Ila was predicted to reach 32% at 15 min and only after 60 min. However, overall, the Ila/Xyl cocrystal showed results equivalent to or exceeding the dissolution rate of Ila. Therefore, it is predicted that the Ila/Xyl cocrystal will maximize ...

The results provide a calibration between the value of Δ E and the probability of cocrystal formation: when the cocrystal is favored by more than 11 kJ mol −1 over the two pure solids, the probability of obtaining a cocrystal is better than 50%. An advantage of this approach is that it is sufficiently fast to be used as a high throughput ...

There is general agreement that the history of co-crystals dates back to 1844 when Friedrich Wöhler combined solutions of quinone and hydroquinone resulting in a green solid, quinhydrone, which he proposed contained both reactants in 1 : 1 stoichiometry. 5 For several decades, there was disagreement about the exact nature of …

Additionally, mechanical properties were evaluated by tensile strength and Heckel analysis of compacts. The cocrystal and CBZ were stored at 40°C/94% RH, 40°C/75% RH, 25°C/60% RH, and 60°C to determine their stability behavior. The cocrystals were fluffy, with a needle-shaped crystal, and were less dense than CBZ.

An anti-solvent slurry method for cocrystal formation is developed and tested in 25 carbamazepine cocrystal systems. With a low solvent/anti-solvent volume ratio, it reduces solubility of reactants and products, and levels out solubility difference of reactants, and consequently generates cocrystals with a higher success rate, higher …

Details of cocrystal habits and important surfaces are listed in Table 1. Due to the smaller total facet area of faces (1 1–1) and (0 0 2) in cocrystal, only the first five faces are considered in the following sections. The cocrystal structure was cleaved along (h k l) indices, and the z-direction was reset normal to the growth faces. The 2 ...
