13548-38-4 Usage

Chemical Properties

Chromium nitrate is a crystalline substance, variously stated to be green brown or purple and existing in various hydrated forms.

Uses

Catalyst, corrosion inhibitor.

Definition

ChEBI: An inorganic nitrate salt consisting of chromium and nitrate in which the ratio of chromium (in the +3 oxidation state) to nitrate is 1:3

Hazard

May ignite organic materials on contact; may be explosive when shocked or heated; powerful oxidizer. Very toxic.

Safety Profile

Poison by intraperitoneal route. Moderately toxic by subcutaneous and ingestion routes. Mutation data reported. Questionable carcinogen. When heated to decomposition it emits toxic fumes of NOx and Cr.

Potential Exposure

Chromium nitrate is used in the preparation of chrome catalysts, in textile printing operations; and as a corrosion inhibitor. Used to make other chemicals.

Shipping

UN2720 Chromium nitrate, Hazard Class: 5.1; Labels: 5.1-Oxidizer

Purification Methods

Filter off the salt and wash it with CCl4 in a closed system under N2, and dry it in vacuo. It is very soluble in H2O, EtOAc and Me2SO but insoluble in *C6H6, CCl4 and CHCl3. The deliquescent powder reacts vigorously with Et2O. [Addison & Chapman J Chem Soc 539 1964.] Cr(VI) ions are carcinogenic as they cause DNA breaks, and Cr(III) ions affect DNA synthesis.

Incompatibilities

This chemical is a strong oxidizer. Contact with reducing agents; fuels, ethers, and other flammable and combustible materials cause a fire and explosion hazard. Violent reaction with many compounds, including reducing agents; alcohols, chemically active metals; combustible materials, strong acids, alkaline earth sulfides, aluminum carbides, aluminum, amines, calcium sulfide, carbides, chlorine trifluoride, glycerin, hydrides, hydrochloric acid, hydrogen peroxide, hydrogen sulfide, hydroxylamine, magnesium, metal powders, metal sulfides, molybdenum, phenylhydrazine, phosphorous red/friction, phosphorous trichloride, silicon, sulfides, sulfur, sulfur Chromium Nitrate 845 dioxide, sulfur/friction, sulfuric acid, tungsten, hydrogen trisulfide

Waste Disposal

Precipitate chromium as the hydroxide. Dewater the sludge and dispose of in singlepurpose dumps.

Check Digit Verification of cas no

The CAS Registry Mumber 13548-38-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,3,5,4 and 8 respectively; the second part has 2 digits, 3 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 13548-38:
(7*1)+(6*3)+(5*5)+(4*4)+(3*8)+(2*3)+(1*8)=104
104 % 10 = 4
So 13548-38-4 is a valid CAS Registry Number.
