CDCl3 is a common solvent used for NMR analysis. It is used because most compounds will dissolve in it, it is volatile and therefore easy to get rid of, and it is non-reactive and will not exchange its deuterium with protons in the molecule being studied.
1,3-Propanediol is the organic compound with the formula CH 2 (CH 2 OH) 2. This three-carbon diol is a colorless viscous liquid that is miscible with water.,3-Propanediol may be chemically synthesized by the hydration of acrolein, or by the hydroformylation of ethylene oxide to afford 3-hydroxypropionaldehyde. The aldehyde is hydrogenated to give 1,3-propanediol.
