Magnesium Chloride Hexahydrate
CAS NO: 7791-18-6
MOLECULAR FORMULA: MgCl2•6H2O
MOLECULAR WEIGHT: 203.30
Application: Magnesium Chloride, Hexahydrate is a source of magnesium ion and a co-foactor for many enzymes Purity: >99% Molecular Weight: 203.3 Molecular Formula: MgCl2•6H2O Description: Magnesium Chloride, Hexahydrate is widely used as a source of magnesium ion in chemistry and molecular biology applications. In biological systems, magnesium is a co-factor for many enzymes including deoxyribonuclease (DNase) and various restriction enzymes. Also plays a role in cell membrane integrity, muscle cell physiology, cardiovascular and muscular activity, and nucleic acid structure. Magnesium chloride solution is a favorable choice as an elution buffer for antibody affinity column purifications; it is much milder on most antigens than acid elution, allowing reuse of the antigen column. Also an essential cofactor for the DNA polymerase in polymerase chain reaction (PCR) amplification. Physical State : Solid Solubility : Soluble in water (20 mg/ml), and alcohol. Storage : Store at room temperature Melting Point : 116-118° C (dec.) Density : 1.57 g/cm3 at 20° C

Potassium Chloride
CAS NO: 7447-40-7
MOLECULAR FORMULA: KCl
MOLECULAR WEIGHT: 74.55
Alternate Names: Potassium Chloride is also known as KCl. Application: Potassium Chloride is a common laboratory reagent and calibration standard for measuring electrical conducivity. Purity: >99% Description: Potassium Chloride is commonly used as a laboratory reagent as a standard. Potassium Chloride may be used as a calibration standard ionic solution for measuring electrical conductivity because Potassium Chloride solutions, when prepared carefully, produce repeatable measurable properties. Potassium Chloride is also a good source of ionic chloride, which should precipitate insoluble chloride salts upon addition to a solution of an appropriate metal ion. Oral Potassium Chloride is commonly used to replenish vital potassium in the body, and has also been shown to lower blood pressure. Potassium Chloride is commonly used in fertilizer. Physical State : Solid Solubility : Soluble in water (340 mg/ml at 20° C), alcohol (slightly), and ethanol (1 g/250 mL). Insoluble in ether, and acetone. Storage : Store at room temperature Melting Point : 770° C (lit.) Boiling Point : 1500° C (lit.) Density : 1.98 g/cm3 at 25° C (lit.)
