Overview
Beijing Huakesheng Fine Chemical Products Trading Co., Ltd. produces and sells Na2EDTA Melvaine buffer solution. Pharmacopoeia: Ethylene diamine tetraacetic acid (EDTA) is an organic compound with the chemical formula C10H16N2O8. It is a white powder at room temperature and pressure. It is a chelating agent that can bind with divalent metal ions such as Mg2+, Ca2+, Mn2+, Fe2+, etc. Due to the fact that most nucleases and some proteases require Mg2+for their action, they are commonly used as inhibitors of nucleases and proteases; It can also be used to remove heavy metal ions. $r $n Chinese name Ethylenediaminetetraacetic acid [2] $r $n External

quality inspection
⑴ Content determination
Using coordination titration method. First, prepare ethylenediaminetetraacetic acid with KOH to form a sample solution with a pH of 12.0~13.0. Using acidic chrome blue K and naphthol green as mixed indicators, titrate the analytical pure CaCO3 dried at 120 ℃ with the sample solution. The endpoint is when the solution changes from purple red to blue-green.
⑵ Determination of Burning Residue
Follow the conventional method.
safety measures
