Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Formula: C6H20CaO11

Physicochemical properties of calcium lactate prepared by single-phase aragonite precipitated calcium carbonate was written by Cheong, Sun Hee. And the article was included in Research Journal of Pharmaceutical, Biological and Chemical Sciences in 2016.Formula: C6H20CaO11 This article mentions the following:

This study sought to prepare calcium lactate using precipitated calcium carbonate (PCC) by reacting lactic acid and then investigated the formation yield and physicochem. properties of synthetic calcium lactate by Fourier Transform IR Spectroscopy (FT-IR), Thermogravimetric-DTA (TG-DTA) and Scanning Electron Microscope (SEM). The strong OH valence band of calcium lactate prepared by PCC in the 3000∼3500 cm-1 region of the FT-IR spectra showed very low intensity. Also it was found that the characteristic carbonyl band was observed at approx. 1500∼1750 cm-1 (C=O stretching) and 1300∼1400 cm-1 (C-H bending), resp. The diffraction profile of synthetic calcium lactate prepared by PCC showed a typical diffraction pattern for a crystalline solid. The TG-DTA curve of calcium lactate showed a rapid decrease at 200∼400 °C due to the m.p. of calcium lactate, which was about 240 °C. In particular, the curve had a second decrease at 600∼800 °C due to the decarbonation of calcium oxide. As for SEM images, calcium lactate using PCC existed as plate-like crystals with smooth surface. These results indicated that calcium lactate pentahydrate was formed by reacting between PCC and lactic acid. In the experiment, the researchers used many compounds, for example, Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5Formula: C6H20CaO11).
