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).

Microbubble Composition and Preparation for High-Frequency Contrast-Enhanced Ultrasound Imaging: In Vitro and In Vivo Evaluation.

Verya Daeichin et al.

IEEE transactions on ultrasonics, ferroelectrics, and frequency control, 64(3), 555-567 (2017-01-24)

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

Universal electronic-cigarette test: physiochemical characterization of reference e-liquid.

Jeffrey J Kim et al.

Tobacco induced diseases, 15, 14-14 (2017-02-28)

Despite the rising health and safety concerns of e-cigarettes, a universal e-cigarette testing method is still in its early developmental stage. The aim of this study was to develop an e-liquid Reference Material that can be used to improve accuracy

Revealing the Physicochemical Basis of Organic Solid-Solid Wetting Deposition: Casimir-like Forces, Hydrophobic Collapse, and the Role of the Zeta Potential.

Alexander Eberle et al.

Journal of the American Chemical Society, 140(4), 1327-1336 (2018-01-10)

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

Human embryo features that influence the success of cryopreservation with the use of 1,2 propanediol.

Fertility and sterility, 44(5), 645-651 (1985-11-01)

Eighty-five human embryos fertilized in vitro were frozen and thawed with 1,2 propanediol as a cryoprotective agent. The effects of viability of in vitro culture duration, stage, and morphologic appearance of embryos were examined after thawing. Survival was higher for
