應用
Potassium nitrite has been used for determining the bacteriostatic and fungistatic activity of acidified nitrite.[1] It has also been used as a supplement in buffer for investigating the impact of nitrite on nosocomial pathogens including C. difficile spores.[2] Adulterants such as “Klear” and “Whizzies” contain potassium nitrite which masks tests for abused drugs in urine. Hence potassium nitrite is used along with Klear and Urine Luck for preparing adulterated urine for drug-of-abuse testing.[3]
生化／生理作用
Potassium nitrite is a strong oxidizing agent that enhances seeds to germinate without a pre-incubation period and without ethylene.[4]

Nitric oxide is generated from sweat nitrite in the acidic environment of the skin surface and is thought to contribute to protection against infection. This study examined the sensitivity of Trichophyton mentagrophytes, T. rubrum, Candida albicans, Streptococcus pyogenes, Staphylococcus aureus

Exposure to pH 1 or 2 buffers or acidic gastric contents resulted in the killing of vancomycin-resistant Enterococcus sp., Klebsiella pneumoniae, Staphylococcus aureus, and Candida glabrata but not Clostridium difficile spores. Nitrite enhanced killing under acidic conditions, but significant killing

Nitric oxide is continually released from normal skin and has antimicrobial effects. An acidified nitrite cream releases supraphysiologic concentrations of nitric oxide and is fungicidal in vitro. The purpose of this study was to assess the efficacy of an acidified

The electrochemical oxidation of potassium nitrite has been studied in the room temperature ionic liquid (RTIL) [C2mim][NTf2] by cyclic voltammetry at platinum electrodes. A chemically irreversible oxidation peak was observed, and a solubility of 7.5(+/-0.5) mM and diffusion coefficient of
