{"knowledge_schema": {"broad_category": "Chemistry \u2192 Organic Chemistry \u2192 Compound Identification", "refinement": "This problem involves identifying an organic compound based on its molecular formula and spectral data (IR and NMR).", "specific_scope": "The task is to analyze the provided IR and NMR data to match the compound C8H9NO3 with one of the given candidates.", "goal": "Determine the correct compound from the list of candidates that corresponds to the molecular formula C8H9NO3 and fits the spectral data."}, "summary": "In this problem, we are tasked with identifying the organic compound C8H9NO3 using IR and NMR spectral data. The IR spectrum shows a strong band at 1740 cm-1, indicating a carbonyl group, and medium intensity bands at 3400 cm-1 and 3300 cm-1, suggesting the presence of an amine or alcohol. The 1H NMR data provides information about the number of hydrogen atoms and their environments, which helps in distinguishing between the candidates. After analyzing the data, the correct identification is Methyl 4-aminobenzoate, as it matches the molecular formula and spectral characteristics."}
