The handbook emphasizes the importance of accurate chemical analysis methods to determine the composition of plastic and polymer additives. Given the complex nature of these materials, traditional analytical techniques such as gravimetry and titration often fall short. Instead, advanced methods like gas chromatography-mass spectrometry (GC-MS), high-performance liquid chromatography (HPLC), and Fourier-transform infrared spectroscopy (FTIR) have become standard tools in the analytical laboratory. These techniques allow for the precise identification and quantification of both organic and inorganic additives in diverse plastic matrices.


Once an API is developed, it undergoes rigorous testing to ensure its safety and efficacy. This includes preclinical studies, often conducted in vitro (in test tubes) and in vivo (in live organisms), followed by multiple phases of clinical trials with human subjects. Each phase aims to assess different aspects, such as dosage safety, effectiveness, and adverse effects. This stringency is crucial, as even small changes in the API's chemistry can significantly affect the drug's performance and safety profile.

The applications of ethylene glycol acetate are extensive and encompass various sectors, including coatings, inks, and pharmaceuticals. In the coatings industry, it is commonly employed as a solvent in paint formulations due to its ability to dissolve a wide range of resins. This characteristic contributes to the improved flow and level of the paint, providing a smoother finish once dried.

In addition to its use in children, sevoflurane is employed in adults, including those with significant comorbidities, thanks to its non-irritating nature and minor respiratory effects. It can be used in patients with reactive airways or those who may not tolerate more typical anesthetic agents.
