Magnesium Nitrate, Hexahydrate, Crystal, Reagent, ACS is extremely soluble in water and in ethanol. It is used in fertilizer blends in the hydroponics and greenhouse trade. It also used as a preservative, catalyst in the manufacture of petrochemicals, as a desensitizer for lithographic plates and in pyrotechnics. As an ACS grade quality reagent, its chemical specifications are the de facto standards for chemicals used in many high-purity applications and typically designate the highest quality chemical available for laboratory use. Spectrum Chemical manufactured Reagent ACS grade products meet the toughest regulatory standards for quality and purity.

Methylbenzene (1 per EA)

Methyl Alcohol, Exceeds A.C.S Specifications, HPLC Grade is a colorless, flammable substance used in chemical labs as a polar protic solvent in organic synthesis, as well as a carrier (mobile phase) solvent in high pressure liquid chromatography (HPLC). Less expensive than Acetonitrile, the popularity Methyl Alcohol HPLC continues to grow, especially in reversed phase HPLC.

All HPLC and Ultra-pure solvents offered by Spectrum are glass distilled, submicron filtered, and undergo rigorous specification testing to insure accurate, repeatable results.

Acetonitrile, Exceeds A.C.S. Specifications, HPLC Grade as a polar aprotic solvent in organic synthesis, as well as a carrier (mobile phase) solvent in high pressure liquid chromatography (HPLC). Acetonitrile is a medium-polarity solvent with a convenient liquid range that is miscible with water and makes it one of the most popular HPLC solvent choices.

All HPLC and Ultra-pure solvents offered by Spectrum are glass distilled, submicron filtered, and undergo rigorous specification testing to insure accurate, repeatable results.

Chloroform, Stabilized, Reagent, ACS, is a colorless, sweet smelling organic compound comes in the form of a dense liquid and is a trihalomethane. It is also commonly used as laboratory solvent because it is relatively unreactive, conveniently volatile and is miscible with most organic compounds. Although it uses as a reagent are limited, it is used in organic synthesis in order to produce dichlorocarbene by reacting with sodium hydroxide. As an ACS grade Reagent, Spectrum Chemical manufactured chloroform is used as the quality standard against which other substances are graded and has met the toughest regulatory standards for quality and pureness.
