Used as a stabilizer in nitrocellulose-based propellants and explosives to prevent premature decomposition by scavenging nitrogen oxides. Commonly found in double-base gun propellants to extend shelf life and maintain stability during storage. Also applied in the detection of nitrate in analytical chemistry, where it serves as a reagent in colorimetric tests, producing a visible blue or violet color in the presence of nitrates. Additionally, used in some antioxidant formulations for rubber and lubricants to inhibit oxidative degradation.
