NMR Spectra for Tri- and Tetrasubstituted Guanidines from Carbodiimide Guanylation

Nuclear magnetic resonance (NMR) spectra for a series of prepared chemical compounds. The dataset, authored by Tomas Chlupaty, is a 122.8 MB ZIP file containing spectra related to the reinvestigation of carbodiimide guanylation reactions. It was last updated on May 4, 2026, and is shared under a CC-BY-4.0 license.

Use Cases

• Validate chemical structures based on provided NMR spectra.
• Benchmark NMR spectral data for newly synthesized tri- and tetrasubstituted guanidines.
• Analyze reaction outcomes for HCl-initiated carbodiimide guanylation.

Strengths

• Dataset size is 122.8 MB, indicating a substantial collection of spectral files.
• Explicitly states the data consists of NMR spectra for prepared compounds.
• Has a specific, recent last updated date of 2026-05-04.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Column-level documentation is absent; file organization and spectral parameters must be inferred after download.
• Row count is unknown, which may limit suitability assessment for quantitative analysis.
