ABSTRACT Rational Benzophenone derivatives, commonly used as UV filters in personal care products (PCPs), are widely prevalent and raise concerns due to their endocrine‐disrupting effects. Sensitive efficient analytical methods demand for detection. In this study, we developed a TAPB‐DMTP‐covalent organic framework (COF) nanofilm‐assisted laser desorption ionization mass spectrometry (LDI‐MS) method the quantitative analysis of 2,4‐dihydroxybenzophenone (BP‐1) PCPs. Methods The TAPB‐DMTP‐COF nanofilm was synthesized on indium tin oxide (ITO) glass utilized an LDI‐MS substrate. performance analyzing small molecules (e.g., benzophenone phthalates, amino acids, sugars, nucleosides) compared conventional matrices (α‐cyano‐4‐hydroxycinnamic acid [CHCA], 2,5‐dihydroxybenzoic [DHB], sinapinic [SA]). reproducibility, salt resistance, sensitivity, stability were further evaluated. Finally, technique applied quantify BP‐1 Results provided stronger spectral signals cleaner backgrounds CHCA, DHB, SA. exhibited high reproducibility (RSD = 6.10%) up 30 days. PCPs quantified with excellent linearity (1–20 μg/mL, r 0.9993), low detection limit (0.3 μg/mL), recovery rates 94.2%–104.4%, demonstrating potential sensitive reliable small‐molecule analysis. Conclusion offered advantages rapid analysis, clean backgrounds, detecting molecules, including derivatives. This successfully PCPs, highlighting its suitability complex samples.
