Specification

The Copper, with the cas registry number 7440-50-8, is a kind of reddish metal. Being stable while incompatible with strong acids, active halogen compounds, chlorine, fluorine, iodine, bromine, ammonia, this chemical may react explosively with strong oxidizing agents. Besides, it is soluble in nitric acid, hot concentrated sulfuric acid while insoluble in cold and hot water.

Its product categories are including Metals; Inorganics; Certified Reference Materials(CRMs); Labware; Metal; Tubing; Analytical/Chromatography; Elemental Analysis; Spectroscopy; Industrial Raw MaterialsReference/Calibration Standards; Reactor DosimetryCertified Reference Materials (CRMs); Alphabetic; Application CRMs; C; CO - CZCertified Reference Materials (CRMs).

The characteristics of this chemical are as below: (1)#H bond acceptors: 0; (2)#H bond donors: 0; (3)#Freely Rotating Bonds: 0; (4)Polar Surface Area: 0; (5)Exact Mass: 62.929601; (6)MonoIsotopic Mass: 62.929601; (7)Heavy Atom Count: 1; (8)Covalently-Bonded Unit Count: 1.

The production method of this chemical is below: Prepare the material of metal cooper to dissolve in the concentrated sulfuric acid to get the electrolyte with the component of Cu 52.3 g/L, H2SO4 200 g/L, with the following condition: electrolyte temperature 58.5℃, slot voltage 0.33 V, cathodic current density 1.82 A/cm2; Next go through the electrolytic refining to get this high purified products.

As to its usage, it is widely applied in many fields. This chemical could be used as the electronic industry material and high purified analysis reagent; It could also be used as powder metallurgy parts, diamond sawblade, friction materials, carbon products and chemical catalyst, and also as the catalyst and reductant.

When you are dealing with this chemical, you should be very cautious. For one thing, it is irritating to eyes and skin and may cause inflammation to the skin or other mucous membranes. For another thing, it is harmful which may cause damage to health. The vapours may cause drowsiness and dizziness and it may have danger of serious damage to health by prolonged exposure. In addition, it is highly flammable which may catch fire in contact with air, only needing brief contact with an ignition source, and it has a very low flash point or evolve highly flammable gases in contact with water. Beside all these, it is dangerous for the environment which may present an immediate or delayed danger to one or more components of the environment. Being toxic to aquatic organisms, it may cause long-term adverse effects in the aquatic environment.

Therefore, you should take different measurs to deal with different cases. Wear suitable protective clothing and gloves. If in case of contact with eyes, rinse immediately with plenty of water and seek medical advice and if swallowed, do not induce vomitting; seek medical advice immediately and show this container or label. When you are storing this chemical, keep away from sources of ignition and then remember not to release to the environment. Then you could also refer to special instructions / safety data sheets.

In addition, you could convert the following datas into the molecular structure:
(1)Canonical SMILES: [Cu]
(2)InChI: InChI=1S/Cu
(3)InChIKey: RYGMFSIKBFXOCR-UHFFFAOYSA-N?
