This chemical product, which is distributed by UBA, is a simple and highly versatile hydracid, due to its very low molecular weight and pronounced acidity.
Further, a purified (S)-α-halomethy-3- pyridinemethanol derivative hydrohalide can be isolated as a crystal from a contaminated (S)-α-halomethyl-3-pyridine- methanol derivative by the use of a hydrohalic acid and an organic solvent.
The betaine compounds, and aqueous, alcoholic or aqueous-alcoholic solutions and dispersions of them, are prepared by betainization of the corresponding tertiary-amine compound with a halo acid or a halo acid salt.
