In order to address the shortcomings of traditional laboratory methods for detecting the stability of propellants, this study explores the use of near-infrared spectroscopy analysis technology for its detection. Establish quantitative analysis models for typical single base and double base drugs based on chemometric software, and apply and validate the models in practical situations. The results showed that the correlation coefficient (RC) of the calibration samples was 0.98, and the relative deviation between external and internal validation was below 5%. The accuracy of the calibration model was good. Compared with traditional detection and analysis methods, near-infrared spectroscopy analysis technology has a qualitative improvement in analysis speed, cost, and environmental protection, achieving rapid, accurate, and environmentally friendly detection of propellant stabilizer content and judgment of propellant stability.
