CAS号: 67-97-0 英文名称: Vitamin D3 英文同义词: WSSD3;Ebivit;Oxarol;Vi-De3;Deparal;rampage;MC 1275;CALCIOL;Prezios;Devaron 中文名称: 维生素 D3 中文同义词: 胆;胆骨化醇;膽成骨醇;膽鈣化醇;维生素D;维生素D3;維他命D3;维生素丁3;維生素D3;维生素 D3 分子式: C27H44O 分子量: 384.64 熔点 : 83-86 °C(lit.) 比旋光度 : 105 º (c=0.8, EtOH 25 ºC) 沸点 : 451.27°C (rough estimate) 密度 : 0.9717 (rough estimate) 蒸气压: 2.0 x l0-6 Pa (20 °C, est.) 折射率 : 1.5100 (estimate) 闪点 : 14 °C 储存条件 : 2-8°C 溶解度 : Practically insoluble in water, freely soluble in ethanol (96 per cent), soluble in trimethylpentane and in fatty oils. It is sensitive to air, heat and light. Solutions in solvents without an antioxidant are unstable and are to be used immediately. A reversible isomerisation to pre-cholecalciferol takes place in solution, depending on temperature and time. The activity is due to both compounds. 形态: powder 酸度系数(pKa): 14.74±0.20(Predicted) 水溶解性 : 敏感性 : Air & Light Sensitive Merck : 14,10019 BRN : 2339331 InChIKey: QYSXJUFSXHHAJI-YRZJJWOYSA-N CAS 数据库: 67-97-0(CAS DataBase Reference) NIST化学物质信息: Cholecalciferol(67-97-0) EPA化学物质信息: Cholecalciferol (67-97-0) 危险品标志 : T+,T,Xn,F 危险类别码 : 24/25-26-48/25-23/24/25-20-11-48 安全说明 : 28-36/37-45-28A-36/37/39-16-7 危险品运输编号 : UN 2811 6.1/PG 2 WGK Germany : 2 RTECS号: VS2900000 F : 8-10-23 TSCA : Yes HazardClass : 6.1 PackingGroup : II 海关编码 : 29130000 海关编码 : 29362990 毒害物质数据: 67-97-0(Hazardous Substances Data) 毒性: LD50 oral in rat: 42mg/kg
