Folic acid (also known as folate, vitamin M, vitamin B9, vitamin Bc (or
folacin), pteroyl-L-glutamic acid, and pteroyl-L-glutamate) are forms of the
water-soluble vitamin B9. Folate is composed of the aromatic pteridine ring
linked to para-aminobenzoic acid and one or more glutamate residues. Folic acid
is itself not biologically active, but its biological importance is due to
tetrahydrofolate and other derivatives after its conversion to dihydrofolic acid
in the liver.

of 4.0-4.8.
Reactivity Profile: Acid solutions of Folic
acid are sensitive to heat, but towards neutrality, stability progressively
increases. Solutions are inactivated
by ultraviolet light and alkaline
solutions are sensitive to oxidation. Folic acid is also inactivated by light.
Folic acid is incompatible with oxidizing agents, reducing agents and heavy
metal ions.
Fire Hazard: Flash point data for Folic acid are not
available; however, Folic acid is probably combustible.
