Products Description

Chemical Properties	Sodium nitrite, NaN02, is a fire-hazardous, air-sensitive, yellowish white powder that is soluble in water and decomposes at temperatures above 320°C (608 °F). Sodium nitrite is used as an intermediate for dye stuffs and for pickling of meat, in dyeing of textiles, in rustproofing, in medicine, and as a reagent in organic chemistry.
Uses 01	Sodium nitrite is a myeloperoxidase inhibitor with IC50 of 1.3 μM
Uses 02	manufacture of diazo dyes, nitroso Compounds, and in many other processes of manufacture of organic chemicals; dyeing and printing textile fabrics; bleaching flax, silk, and linen; photography. In meat curing, coloring and preserving; in processing smoked chub. Also as reagent In animal chemistry.
Uses 03	Sodium Nitrite is the salt of nitrous acid that functions as an anti- microbial agent and preservative. it is a slightly yellow granular powder or nearly white, opaque mass or sticks. it is deliquescent in air. it has a solubility of 1 g in 1.5 ml of water. it is used in meat cur- ing for color fixation and development of flavor. see nitrite.

Description

Sodium nitrite is the inorganic compound with the chemical formula NaNO2. It is a white to slightly yellowish crystalline powder that is very soluble in water and is hygroscopic. It is a useful precursor to a variety of organic compounds, such as pharmaceuticals, dyes, and pesticides, but it is probably best known as a food additive to prevent botulism.
It is on the World Health Organization's List of Essential Medicines, the most important medications needed in a basic health system.
