Descrição geral
Formaldehyde-sodium bisulfite adduct is used as a standard in the synthesis of 3-Hydroxypropionaldehyde (3HPA). It can be assayed by HPLC with fluorometric detection in selected foods.
Aplicação
- Triethyl citrate as a non-toxic solvent in pharmaceutical applications: Explored the use of Triethyl citrate in in-situ forming PLGA implants, focusing on its role as a less toxic solvent compared to traditional options. This application demonstrates the importance of Triethyl citrate in developing safer pharmaceutical formulations (Ramos et al., 2024).
- Triethyl citrate in biodegradable polymer research: Examines the influence of Triethyl citrate on the melt spinning and structural properties of poly(lactic acid) fibers. This study highlights its effectiveness as a plasticizer, enhancing the processability and properties of biodegradable polymers, relevant for controlled drug release systems (Gzyra-Jagieła et al., 2024).

A rapid and accurate method for measuring low part-per-million levels of free and reversibly-bound sulfites in selected foods by using high-performance liquid chromatography (HPLC) with fluorometric detection was developed. Sulfites were extracted with sodium tetrachloromercurate solution and determined by HPLC-fluorescence
