Copyright and ownership

IntoChemistry publishes original chemistry explanations, learning activities, designs and educational resources, along with material from third parties where separately identified. Copyright in original contributions is claimed by the applicable rights holder; material credited to other authors remains subject to their own licenses or permissions. The scientific facts, chemical equations, methods and general subject matter discussed here are not claimed as proprietary.

Research citations and educational accuracy

References in articles support stated scientific claims and help readers find the original studies. A citation is not itself a license to reproduce someone else’s words, photographs, figures or assessments. We seek to write independent explanations, identify data sources and distinguish published findings from original examples or illustrations. Scientific errors or attribution concerns can be reported using our contact page.

PubChem chemical structures

Some two-dimensional chemical diagrams are sourced from the U.S. National Library of Medicine’s PubChem structure images. PubChem allows reuse of its 2D and 3D structure images without special permission and requests citation to the relevant record. Examples displayed on IntoChemistry include creatine (CID 586), DHA (CID 445580), EPA (CID 446284), and bacoside A3 (CID 91827005). Structural drawings that are expressly identified as new IntoChemistry illustrations are distinguished from reused PubChem image files.

Textbook companion guides and external resources

IntoChemistry is an independent educational publisher and is not affiliated with or endorsed by Pearson, McGraw Hill, OpenStax, the American Chemical Society, or the Association of American Medical Colleges unless expressly stated. References to authors, books, chapter titles and editions identify the resources students use; IntoChemistry chapter companions are not official textbook editions or reproductions of textbook chapters.

OpenStax Chemistry 2e is licensed CC BY-NC-SA 4.0. Linking students to the freely available book does not mean its text, art, problems or assessments can be republished in commercial materials without appropriate authorization. Materials created independently around chemistry concepts are distinguished from OpenStax adaptations.

MCAT® is a trademark of the Association of American Medical Colleges (AAMC). IntoChemistry’s MCAT-style exercises are unofficial independent chemistry practice, not AAMC-approved examinations or score predictors. Published official exam questions and passages are not licensed for redistribution by a mere source citation.

Illustrations and AI-assisted works

Some original illustrations or text may be created with digital or AI-assisted tools and then selected, reviewed and edited for educational use. Such material is not represented as an original photograph of an experiment unless it is one. Copyright eligibility depends on applicable law and the extent of human authorship; IntoChemistry does not claim exclusive rights in scientific facts or in third-party contributions.

Permissions, reuse and corrections

For reuse of IntoChemistry educational products, follow the license supplied with the specific product. An IntoChemistry copyright notice does not override separately credited CC or public-domain material. To request permission or report an ownership, credit, licensing, or factual issue, contact IntoChemistry and include the page URL, the affected item, a source link and the correction requested. We review substantiated reports and may revise, credit or withdraw material as appropriate.

OpenStax organic chemistry: John McMurry, Organic Chemistry: A Tenth Edition (OpenStax, 2023), is also licensed under CC BY-NC-SA 4.0. The copyright in its explanations, original artwork and assessments remains separate from IntoChemistry. Direct links and attribution do not authorize commercial reuse. Original chemistry principles and independently written examples may be taught without reproducing publisher expression.

Laboratory safety framework sources

Some IntoChemistry lab worksheets and instructor manuals apply the RAMP framework (Recognize hazards, Assess risks, Minimize risks, Prepare for emergencies). The framework is explained by the American Chemical Society, What Is RAMP?; consult also ACS, Guidelines for Chemical Laboratory Safety in Academic Institutions (2016). RAMP-related concepts are acknowledged as sourced safety methodology, not claimed as an IntoChemistry invention. The credited ACS publications retain their own copyright, and citation does not grant permission to republish them. These independent teaching resources are not endorsed or safety-certified by ACS or by a laboratory institution.
