Use	Used for reduction and hydroboration reactions. Used as a pharmaceutical intermediate The energy distribution function analysis of the tote isotherm of gas absorption on the heterogeneous surface. & bull preparation of α-alkyl-β-hydroxy esters & bull selectively immobilized short-chain oligonucleotides in acrylic copolymer gels. Preparation of immunoglobulins paired with viral antigens & sintering of bull silicon carbide & bull reduces the solvent used in high performance liquid chromatographic analysis of oligosaccharides. The modification of & bull catalytic slurry affects the process of carbonization into mesophase pitch
Production method	Pass dry hydrogen chloride gas into the anhydrous ether solution of pyridine, filter out the solid pyridine hydrochloride, and suspend it after drying In the pyridine, add the pyridine solution of sodium borohydride, and react at room temperature. Then filter out the sodium chloride precipitation in the reactants, evaporate the pyridine under reduced pressure at 50°C, and add an equal volume of anhydrous ether to precipitate the unreacted pyridine hydrochloride. Filter and steam under reduced pressure to remove ether to obtain the finished product.
