General description

1,2-Propanediol is a 1,2-alkanediol. It can be obtained from glycerol, via hydrogenolysis in the presence of Ru/C and Amberlyst ion-exchange resins.

Application

1,2-Propanediol (propanediol) may be employed as a cryoprotective agent for the preservation (by cooling to sub-zero temperatures) of human embryos and oocytes (human and mouse).

Supramolecular self-assembly at the solid-solid interface enables the deposition and monolayer formation of insoluble organic semiconductors under ambient conditions. The underlying process, termed as the organic solid-solid wetting deposition (OSWD), generates two-dimensional adsorbates directly from dispersed three-dimensional organic crystals. This

Although high-frequency ultrasound imaging is gaining attention in various applications, hardly any ultrasound contrast agents (UCAs) dedicated to such frequencies (>15 MHz) are available for contrast-enhanced ultrasound (CEUS) imaging. Moreover, the composition of the limited commercially available UCAs for high-frequency
