General description

Sodium chlorate is a sodium salt. It has been reported to exhibit piezoelectric effect.[1] On heating, it decomposes to give sodium chloride and sodium perchlorate. It can be synthesized in the laboratory by reacting chlorine gas with a hot aqueous solution of sodium hydroxide or sodium carbonate.[2]

Biochem/physiol Actions

sulfation biosynthesis inhibitor

Other Notes

Oxidant for the decomposition by oxidation[3][4]

Embryonic stem (ES) cells continuously decide whether to maintain pluripotency or differentiate. While exogenous leukemia inhibitory factor and BMP4 perpetuate a pluripotent state, less is known about the factors initiating differentiation.

A single-chirality solid phase can be obtained in boiling solutions containing a racemic mixture of left- and right-handed enantiomorphous crystals due to dissolution-crystallization cycles induced by a temperature gradient.
