Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5) belongs to alcohols. Similar to water, an alcohol can be pictured as having an sp3 hybridized tetrahedral oxygen atom with nonbonding pairs of electrons occupying two of the four sp3 hybrid orbitals. Tertiary alcohols cannot be oxidized at all without breaking carbon-carbon bonds, whereas primary alcohols can be oxidized to aldehydes or further oxidized to carboxylic acids.Application of 5743-47-5

Effects of calcium salts on thermal characteristics of hydroxypropyl methylcellulose films was written by Sakata, Yukoh;Yamaguchi, Hiroyuki. And the article was included in Journal of Non-Crystalline Solids in 2011.Application of 5743-47-5 This article mentions the following:

Cast films comprising hydroxypropyl methylcellulose (HPMC) and calcium chloride (CaCl2) have higher flexibility than those with HPMC and calcium lactate pentahydrate (CLP). The aim of the present study was to investigate the relationship between the mol. behavior and the film flexibility of HPMC cast films. In differential scanning calorimetry (DSC) measurements, the HPMC-only cast films exhibited a glass transition temperature (Tg) of 142.1-143.9 °C, which is similar that of HPMC/CLP cast films. In contrast, HPMC/CaCl2 cast films exhibited Tg of 76.1-77.3 °C, which is lower than that of HPMC-only and HPMC/CLP films. Thermal mech. anal. (TMA) results indicated that the HPMC-only and HPMC/CLP cast films contracted strongly around the Tg calculated using DSC. In contrast, the cast films comprising HPMC/CaCl2 blends gradually contracted as the temperature increased; this behavior is significantly different from that observed in the HPMC-only and HPMC/CLP films. The most probable mechanism for the film flexibility of HPMC/calcium salt blends was clarified through attenuated total reflection Fourier transform-IR (ATR FT-IR) and thermogravimetric (TG) anal. The anal. results suggest that the difference in the flexibility of the cast films in the presence of CaCl2 or CLP depends on the difference affinity between calcium salts and water mols. In the experiment, the researchers used many compounds, for example, Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5Application of 5743-47-5).
