Description

Application

(S)-(+)-1,2-Propanediol can be used as a reactant to synthesize:

Optically active chiral (S)-1, 2-propanediol derivatives using mesogenic carboxylic acids via esterification in the presence of dimethylaminopyridine (DMAP) as a catalyst.
3,4-Ethylenedioxythiophenes via Mitsunobu reaction.
Vicinal diol cyclic sulfates in the presence of sodium periodate and ruthenium chloride as catalysts.

Adaptive evolution of Escherichia coli K-12 MG1655 during growth on a Nonnative carbon source, L-1,2-propanediol.

Dae-Hee Lee et al.

Applied and environmental microbiology, 76(13), 4158-4168 (2010-05-04)

Laboratory adaptive evolution studies can provide key information to address a wide range of issues in evolutionary biology. Such studies have been limited thus far by the inability of workers to readily detect mutations in evolved microbial strains on a

Cryopreservation of rabbit semen: comparing the effects of different cryoprotectants, cryoprotectant-free vitrification, and the use of albumin plus osmoprotectants on sperm survival and fertility after standard vapor freezing and vitrification.

Maria Pina Rosato et al.

Theriogenology, 79(3), 508-516 (2012-12-12)

This study was designed to improve current freezing protocols for rabbit sperm by examining: (1) the toxicity of different permeable cryoprotectants (CPAs) used for standard vapor freezing (conventional freezing); (2) the feasibility of ultrarapid nonequilibrium freezing (vitrification) of sperm in
