It is important to distinguish between the two main projects:

| Feature | | NIST WebBook | PubChem | | :--- | :--- | :--- | :--- | | Data Type | Evaluated/Consistent | Evaluated & Experimental | Aggregated/Raw | | Focus | Process Design/Thermodynamics | Thermophysics/Chemistry | General Biology/Chemistry | | Consistency | High (Thermodynamic checks) | High | Variable | | Cost | High (Subscription) | Free | Free | | Ease of Access | Moderate | High | High | It is important to distinguish between the two

| Industry | Use | |----------|-----| | Oil & Gas | Vapor-liquid equilibrium for separations | | Specialty Chemicals | Heat capacity for reactor design | | Pharmaceuticals | Solubility and density for crystallization | | Environmental | Biodegradation and toxicity for permits | | Academic Research | Benchmarking molecular simulations (e.g., Force fields) | Force fields) |
