| Resumo≠ | Recrystallization is a classical purification technique in which a solid compound is dissolved in hot solvent, then allowed to crystallize upon cooling, yielding pure crystals while impurities remain in solution. Practiced for centuries in chemistry laboratories, recrystallization remains one of the most effective and accessible methods for purifying organic solids, especially when the target compound has low solubility at low temperatures. | Synthesis route planning, grounded in retrosynthetic analysis, is a strategic approach to designing efficient chemical syntheses. Formalized by Elias James Corey in the 1960s (earning him the Nobel Prize in 1990), this methodology systematically deconstructs target molecules into simpler precursors and starting materials, enabling chemists to discover logical, economical, and practical synthesis routes. | Thin-Layer Chromatography (TLC) is a planar chromatographic technique that separates compounds based on their differential affinities for a mobile and stationary phase. Developed by Egon Stahl in 1956, TLC remains one of the most accessible and widely used analytical methods in organic and inorganic chemistry, laboratories, and quality control. |
