Biological buffers are useful for cell culture in vitro, enzyme assays and some electrophoretic applications at physiological pH. Universally applicable buffers for biochemistry must be water soluble, not interfere with biological processes or biological membranes (penetration, solubilization, adsorption on surface, etc.), have known complex-forming tendency with metal ions, be non-toxic and have a very low U.V. absorption at wavelength >260 nm.

二苯基羰酰二肼,现货供应

英文名称:Diphenylcartazide;1,5-Diphenylcarbazide;1,5-Diphenylcarbohydrazide
其他名称:二苯氨基脲;二苯卡巴肼;二苯基碳酰二肼;1,5-二苯羰酰肼;均二苯卡巴肼;对称二苯基羰二肼;二苯偕肼;羰代双苯肼;二苯碳酰二肼;对称二苯氨基脲;1,5-二苯基卡巴肼
CAS号:140-22-7
C13H14N4O=242.28
级别:AR
熔点:170~174℃
铬酸盐络合物摩尔吸收系数,ε/(L/cm·mol):≥3.8×104
乙醇溶解试验:合格
灼烧残渣(硫酸盐计):≤0.10%
性状(以下信息仅供参考):白色或浅粉红色结晶性粉未,露置空气中逐渐变为红色。微溶于水(~0.024g/100ml),不溶于醚,溶于乙醇、丙酮等其它有机溶剂。溶液比固体易氧化,逐渐变为黄和棕色。试剂和多种金属发生有色反应:Ag+(紫)、Ni2+(蓝)Pb2+(橙蓝)。试剂与CrO42-的反应机理至今还不完全清楚,有人认为是二苯碳酰二肼由CrO42-氧化为二苯缩氨基脲,后者再与Cr3+形成络合物。所形成的络合物阳离子与Cl-结合成离子对,可为戊醇萃取。Cu2+、Fe2+、Hg+、Hg2+、Se4+和TcO4-与试剂反应的原理类似于CrO42-的反应,即氧化还原和络合反应
用途:本品仅供科研,不得用于其它用途。(以下用途仅供参考)滴定铁时作指示剂。比色测定铬、汞和铅,检测镉、汞、镁、醛类和土根碱。测定重铬酸盐的氯化还原指示剂。汞量法测定氯化物和氰化物的吸附指示剂。( 用作分光光度法测定铬的显色剂及检定Cu2+、Fe3+、Hg2+等的显色剂。还用作氧化还原、吸附及配合滴定的指示剂。)
