About ChemWhat

ChemWhat is a database of chemicals & biologicals with the concept “Precision, Completeness, Efficiency”. Since the launch in early 2019, ChemWhat has become a key chemical information resource for scientists, students, and the general public. Each month our websites provide data to several million users worldwide.

ChemWhat mostly contains small molecules, but also larger molecules such as nucleotides, carbohydrates, lipids, peptides, and chemically-modified macromolecules. We collect information on chemical structures, identification, chemical and physical properties, biological activities, route of synthesis (ROS), spectrums, patents, health, safety, toxicity data, storage, transportation, usage, market price and many others.

ChemWhat has launched 21 language sites, including English, German, French, Spanish, Portuguese, Italian, Polish, Russian, Ukrainian, Hindi, Urdu, Bengali, Arabic, Persian, Hebrew, Turkish, Korean, Indonesian, Japanese, Traditional Chinese and Simplified Chinese.

The amount of data and support languages in ChemWhat is ever-growing. At the same time, ChemWhat handles tens of thousands of requests from universities and research institutions worldwide for authorized use of specific information on chemicals and biologicals every day.


In the first half of 2024, ChemWhat AI was officially launched on the ChemWhat website. By leveraging advanced artificial intelligence and ChemWhat high-quality database, ChemWhat AI Chemist provides researchers with highly accurate and relevant data tailored to their specific needs. This precision ensures that researchers can trust the information they retrieve, minimizing errors and enhancing the reliability of their work. More importantly, the applications provided by the ChemWhat AI chemist are currently completely free of charge.

The platform’s comprehensive approach integrates data from a wide array of sources, including scientific journals, ChemWhat databases, and paid repositories. This completeness allows researchers to conduct thorough searches without the need to navigate multiple platforms, saving valuable time and effort. ChemWhat AI Chemist’s extensive data coverage ensures that researchers have access to the most relevant and up-to-date information, facilitating more informed decision-making and innovative discoveries.

Efficiency is at the core of ChemWhat AI Chemist’s design. The platform streamlines the information retrieval process, utilizing sophisticated search algorithms and intuitive interfaces to provide quick and easy access to crucial data. This efficiency not only accelerates the research process but also enhances productivity, allowing researchers to focus more on analysis and experimentation rather than data collection.

Through its commitment to precision, completeness, and efficiency, ChemWhat AI Chemist is transforming the landscape of chemical and biological information retrieval, empowering researchers to achieve greater accuracy and innovation in their work.

The landscape of chemical and biological research is fraught with challenges, from navigating the vast seas of information overload to the prohibitive costs of accessing high-quality databases. However, ChemWhat AI Chemist is poised to transform this field with its commitment to precision, completeness, and efficiency. By leveraging advanced AI technology, ChemWhat offers researchers a powerful tool to streamline their search processes and elevate the quality of their work. As we look to the future of research, tools like ChemWhat AI Chemist will be instrumental in overcoming the complex information barriers that currently impede scientific progress. By integrating these innovative solutions, researchers can focus on deeper analysis and groundbreaking discoveries, ultimately advancing our understanding of chemistry and biology.

In the realm of chemical and biological raw materials, ChemWhat is dedicated to providing “luxury goods” for scientific research. These materials, characterized by extremely high purity, unique manufacturing processes, superior research applications, and impeccable customer experiences, have become the sought-after goals of researchers. These raw materials not only drive scientific progress but also provide reliable tools for researchers worldwide, enabling them to continually make breakthroughs and achieve remarkable accomplishments in their fields. Just as luxury goods bring luxury and enjoyment to life, top-tier raw materials bring precision and success to scientific research.

ChemWhat offers metal catalytic materials such as tungsten and chromium carbonyls with a purity of 99.9999% (6N) or higher, making them the luxuries of the chemical world. These high-purity materials not only meet the stringent precision manufacturing requirements of the semiconductor industry but also drive continuous technological advancement. Just as luxury products rely on top-grade raw materials, these materials depend on the highest purity levels to ensure their superior performance.

Luxury items are revered for their scarcity and unique manufacturing processes. In the field of in vitro diagnostic materials, ChemWhat controls the levels of metals such as copper and iron in certain materials to the ppb (parts per billion) level, demonstrating an astounding level of precision. This extreme purity control requires highly advanced technology and equipment. These materials not only consume significant resources and time during production but also stand out for their rarity and value.

The application of high-end materials in scientific research further highlights their luxury status. ChemWhat has researched and developed top-tier pharmaceutical reference standards, isotope-labeled products, and metabolites widely used in the R&D and regulatory processes of pharmaceutical companies. These materials ensure the accuracy and reliability of every step of experimentation, providing a solid foundation for scientific research. Just as luxury items help individuals stand out in important events, these top-tier materials empower researchers to achieve breakthrough results in their studies.
