1. Acceptance of Terms

By accessing and using ChemRefHub (https://chem-ref.web.app), you accept and agree to be bound by these Terms of Service. If you do not agree, do not use this website.

2. Description of Service

ChemRefHub is a free, independent chemical properties and material compatibility reference database. We provide CAS-indexed physical properties, GHS hazard classifications, 2D molecular structures, and industrial material compatibility matrices sourced from PubChem, ECHA, and manufacturer technical datasheets. The service is provided "as is" for informational purposes only.

3. User Responsibilities

You agree to: (a) use the site only for lawful purposes; (b) not bulk-scrape or redistribute the database without written permission; (c) not misrepresent compatibility data as manufacturer-certified; (d) always verify compatibility ratings with manufacturer TDS before specifying materials for critical applications.

4. Intellectual Property

The compilation, structure, and presentation of data on ChemRefHub are protected by copyright. Individual chemical data points are sourced from publicly available databases (PubChem, ECHA) and manufacturer publications. The ChemRefHub name, logo, and site design are trademarks of this project.

5. Disclaimer

Compatibility ratings are general guidelines. Actual chemical resistance depends on temperature, concentration, and exposure duration. Always verify with manufacturer TDS before specifying materials for critical applications. ChemRefHub does not guarantee the accuracy or completeness of any data point.

6. Limitation of Liability

To the fullest extent permitted by law, ChemRefHub disclaims all liability for material failure, chemical spills, equipment damage, or injuries resulting from reliance on compatibility data provided on this site. Use of this data in material selection decisions is at your sole risk.

7. Third-Party Links

This site contains links to PubChem, ECHA, and manufacturer websites. We are not responsible for the content, accuracy, or availability of third-party sites. Links do not imply endorsement.

8. Changes to Terms

We may update these Terms at any time. Changes will be posted on this page with an updated revision date. Continued use of the site after changes constitutes acceptance of the revised Terms.
