바요주석 C화학적 특성, 용도, 생산

화학적 성질

White powder

용도

vasodilator

용도

vitamin B complex

용도

Growth factor present in minute amounts in every living cell. Plays an indispensable role in numerous naturally occurring carboxylation reactions. Occurs mainly bound to proteins or polypeptides. The richest sources are liver, kidney, pancreas, yeast, and milk. The biotin content of cancerous tumors is higher than that of normal tissue.

정의

ChEBI: An organic heterobicyclic compound that consists of 2-oxohexahydro-1H-thieno[3,4-d]imidazole having a valeric acid substituent attached to the tetrahydrothiophene ring. The parent of the class of biotins.

상표명

Bioepiderm (Sterling Winthrop).

Safety Profile

An experimental teratogen. Experimental reproductive effects. When heated to decomposition it emits toxic fumes of NOx and SOx.

Purification Methods

D-(+)-Biotin crystallises from hot water in fine long needles with a solubility of 22 mg/100mL at 25o. Its solubility in 95% EtOH is 80 mg/100 mL at 25o. Its isoelectric point is at pH 3.5. Store solid and solutions under sterile conditions because it is susceptible to mould growth. [Confalone J Am Chem Soc 97 5936 1975, Wolf et al. J Am Chem Soc 67 2100 1945, Synthesis: Ohuri & Emoto Tetrahedron Lett 2765 1975, Harris et al. J Am Chem Soc 66 1756 1944.] The (+)-methyl ester has m 166-167o (from MeOH/Et2O), [] D 22 +57o (c 1, CHCl3) [du Vigneaud et al. J Biol Chem 140 643, 763 1941]; the (+)-S-oxide has m 200-203o, [] D 20 +130o (c 1.2, 0.1N NaOH) [Melville J Biol Chem 208 495 1954]; the SS-dioxide has m 274-275o(dec, 268-270o), and the SS-dioxide methyl ester has m 239-241o (from MeOH/Et2O) [Hofmann et al. J Biol Chem 141 207, 213 1941]. [Beilstein 27 III/IV 7979.]
