Chemical Structure
Description
Owing to an inorganic composition, 7758-09-0 794654G42L Potassium nitrite Potassium nitrite (1:1) Nitrous acid, potassium salt (1:1) Nitrous acid, potassium salt Caswell No. 698 CCRIS 3959 EINECS 231-832-4 EPA Pesticide Chemical Code 076203 HSDB 1216 UNII-794654G42L Potassium nitrite [UN1488] [Oxidizer] UN1488 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 85.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
