Basic Info of Cupferron


What is Cupferron?

Copper iron reagent is an important analytical reagent, which is the ammonium salt of N-nitrosohydroxylamine, commonly known as copper iron spirit. Normally, it is white or light yellow bright scaly crystals with a sweet taste. The color will become darker due to the slow decomposition of long-term storage, but in fact, it can be used in analysis. It is easily soluble in water, benzene, alcohol, and ether. The reagent is decomposed by heat to generate nitrobenzene. It is unstable in light and air and needs to be stored in a brown grinded reagent bottle. Usually a small amount of ammonium carbonate wrapped in paper or cloth is placed in the bottle as a preservative, and placed in a sealed, dark and cool place. It can be used as a precipitation agent and solvent extraction agent for copper, iron, tin, titanium, vanadium, chromium and other elements, and as a masking agent for the determination of rare earths.

Reduce nitrobenzene with zinc powder in aqueous ammonium chloride solution to obtain phenylhydroxyl, then dissolve the latter in ether, pass in excess ammonia gas, and add n-butyl nitrite to obtain copper-iron reagent. It forms a stable five-membered ring chelate with a variety of metal ions, so it is a commonly used organic precipitant. It can quantitatively determine Fe3+ ions in strong acid solutions, as well as Cu2+, Sn4+, Ti4+, Ga3+, Hf4+ plasma and vanadate (VO-3, VO3-3). When Fe3+, Cu2+ ions are mixed with other metal ions, this reagent can be used to separate them. It is also a chelating extractant for Al3+, Au3+, Be2+, ​​Co2+, La3+, Pu4+ plasma and a masking agent for the determination of rare earth metal ions.

Use of Cupferron in Inorganic Analysis

  1. Chemical analysis reagents for determination of aluminum, copper, iron, titanium, zirconium and other metals.
  2. Cupferron used for quantitative analysis of aluminum, bismuth, copper, iron, gallium, mercury, manganese, niobium, tin, tantalum, thorium, titanium, vanadium, zirconium and other elements.
  3. Polymerization inhibitor, due to Cupferron’s unique polymerization inhibitory characteristics and small dosage, it can be used as a substitute product for phenol polymerization inhibitor BHT, which is currently widely used.
  4. Colorimetric determination of weight determination of aluminum, bismuth, copper, iron mercury, zinc, manganese, niobium, gallium, tantalum, thorium, titanium, vanadium, tin and other elements. Quantitative determination of iron in a strong acid solution, quantitative analysis of vanadate, separation of copper and iron when together with other metals, and a masking agent when measuring rare earths.
  5. Cupferron used to separate copper and iron from other metal ions and to determine iron by precipitation from strong acid solutions; for quantitative determination of vanadate to form dark red precipitates and quantitative determination of titanium to form yellow precipitates; for colorimetric determination of aluminum.

Great company! thanks from Australia for good product quality, correct product, good customer service using chat.. delivery speed was ok, via FedEx. the Alibaba App finally makes it safer, so good companies like Shandong Zhi Shang can do business with us, I don't have to worry now with Alipay. Everything is safe for me now, I can't go wrong. frst time payments can just use card, the seller never knows your details, only Alibaba does the payment, so the risk is gone, delivery on time is guaranteed, and because the seller can't see your card details, scammers can't use this system, only good companies that do the right thing can make money here. it really is a much better system now.

I general, was very satisfied with the supplier. Basic analyzes (m.p.. FTIR) of the product in our facility confirmed its high quality. Further analyzes are planned, but due to the COVID-19 pandemic, most laboratories in Slovenia are closed.
