| Introduction | 1, 10-phenanthroline monohydrate is an organic intermediate, white crystalline powder. 1, 10-phenanthroline monohydrate is a redox indicator, a reagent for the determination of ferrous, palladium, vanadium, copper and iron. |
| storage and transportation information | dangerous goods mark: T N description risk term: R25; R50/53; Description safety term: S45; s60; S61 |
| features | can form complexes with a variety of transition metals, because the formed complexes are chelates, so it is relatively stable. The complexes formed with copper and their derivatives can be used as non-oxidative nucleic acid cleavage enzymes because they have a certain cleavage activity on DNA, and thus have a certain anti-cancer activity. |
| Use | is a commonly used ligand for spectrometric metal and spectral analysis of CO2 reduction. For Cu(II) catalyzed crosslinking reaction of organic boric acid and the like, it can also be used as a redox indicator, a reagent for measuring titanium iron. A complex was formed with iron, copper, cobalt, nickel and 2,2 '-bipyridine, and a red complex was formed with Fe2, 2'-dipyridyl -3,3 '-dicarboxylic acid. it can be used as a quantitative colorimetric reagent for copper and iron, as an indicator for titrating iron salts with cerium sulfate, and as a dye for animal fibers. phenanthroline-Fe(II) indicator can be obtained by combining 1.485g of phenanthroline with 0.695G of feso4? 7H2O was dissolved in 100ml water to prepare. An indicator for the titration of iron salts with cerium sulfate. One related ligand is phenanthroline (BPT),4, 7-diphenyl-1, 10-phenanthroline. O-Phenanthroline can also be used for the analysis of the content of alkyl lithium compounds. The specific step is to allow the sample to react with a small amount (about 1mg) of O-Phenanthroline in a dark color and then titrate with alcohols until a colorless titration end point is reached. in the solution of pH = 2~9, the color reaction of O-Phenanthroline with ferrous ion (Fe2) is very high selectivity, and the formation of orange-red complex is very stable, lgK stable = 21.3(20 deg C), the solution in 510nm (visible light) has the maximum absorption peak, the use of this color reaction, can be determined by visible spectrophotometry trace iron. electroplating additives, Analytical reagents. sensitive reagents for the determination of ferrous iron |
