Strontium nitrate is an inorganic salt composed of strontium, nitrogen, and oxygen, primarily used in pyrotechnics for red flame effects, in red signal and road flares, and in chemical analysis for precipitation reactions. It appears as a white, hygroscopic crystalline solid with high solubility in water. Catalogue details include a CAS number of 10042-76-9, molecular formula Sr(NO₃)₂, and a molecular weight of 211.63 g/mol. Store at ambient conditions, but handle with care: it carries a Danger signal word because it is a strong oxidiser that may cause fire or explosion, is harmful if swallowed, and causes serious eye damage. Molekula supplies strontium nitrate from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
