Salts, Cocrystals, and Ionic Cocrystals of a “Simple” Tautomeric Compound [PDF]

open access: yesCrystal Growth & Design, 2018
We have investigated the cocrystallisation behaviour of AHMP (2-amino-6-methyl-1,4-dihydropyrimidin-4-one) with a series of acids and imide coformers.Being a base able to tautomerise, at the molecular level, AHMP may exist as three different neutral tautomers or, if protonated, in the form of several cationic species.

Obtaining Cocrystals by Reaction Crystallization Method: Pharmaceutical Applications

open access: yesPharmaceutics, 2021
Cocrystals have gained attention in the pharmaceutical industry due to their ability to improve solubility, stability, in vitro dissolution rate, and bioavailability of poorly soluble drugs. Conceptually, cocrystals are multicomponent solids that contain

Site selectivity of halogen oxygen bonding in 5- and 6-haloderivatives of uracil [PDF]

open access: yes, 2019
Seven 5-and 6-halogenated derivatives of uracil or 1-methyluracil (halogen = Cl, Br, I) were studied by single crystal X-ray diffraction. In contrast with pure 5-halouracils, where the presence of N-H…O and C-H…O hydrogen bonds prevents the formation ...

Energetic Cocrystals – Structural Studies of Nitrotriazolone Salts & Cocrystals [PDF]

open access: yesActa Crystallographica Section A Foundations and Advances, 2014
Developments in energetic materials are currently focused on the requirements for safer, yet still powerful materials for uses within mining, munitions and rocket propulsion systems One strategy that can be used to achieve these desirable properties is to synthesise new molecules, but this is both time-consuming and resource-intensive. Instead, another

Recent Advances in Pharmaceutical Cocrystals: A Focused Review of Flavonoid Cocrystals

open access: yesMolecules, 2023
Cocrystallization is currently an attractive technique for tailoring the physicochemical properties of active pharmaceutical ingredients (APIs). Flavonoids are a large class of natural products with a wide range of beneficial properties, including anticancer, anti-inflammatory, antiviral and antioxidant properties, which makes them extensively studied.

Pharmaceutical Cocrystals

open access: yesProcedia Chemistry, 2014
AbstractCocrystals are very interesting and useful product. In this paper the main information about cocrystals is presented. It is shown that cocrystals are solid substances, which consist of few components mixed together. There are a lot of ways of cocrystals production and application.
