Strontium nitrate

This colorless solid is used as a red colorant and oxidizer in pyrotechnics.

[3] Strontium nitrate can aid in eliminating and lessening skin irritations.

When mixed with glycolic acid, strontium nitrate reduces the sensation of skin irritation significantly better than using glycolic acid alone.

[4] As a divalent ion with an ionic radius similar to that of Ca2+ (1.13 Å and 0.99 Å respectively), Sr2+ ions resembles calcium's ability to traverse calcium-selective ion channels and trigger neurotransmitter release from nerve endings.

In his short story "A Germ-Destroyer", Rudyard Kipling refers to strontium nitrate as the main ingredient of the titular fumigant.

NFPA 704 four-colored diamond Health 2: Intense or continued but not chronic exposure could cause temporary incapacitation or possible residual injury. E.g. chloroform Flammability 0: Will not burn. E.g. water Instability 0: Normally stable, even under fire exposure conditions, and is not reactive with water. E.g. liquid nitrogen Special hazard OX: Oxidizer. E.g. potassium perchlorate
