Biochemicals for Life Science Research

Custom and Bulk Chemical Services

When your projects require you to go beyond the catalog, save time and resources by turning to Thermo Fisher Scientific. We offer custom chemicals, bulk, specialized testing, and tailored packaging solutions to meet your research and development needs.

Our Thermo Scientific Chemical-labeled products can be customized to meet your requirements at locations throughout the world.

Our experienced development and production teams can deliver a variety of products to meet the needs of customers in research fields ranging from pharmaceuticals to semiconductors, structural materials, and imaging.


Building blocks for organic synthesis

Chemical synthesis reagents are essential to transform building blocks into target molecules quickly, safely, and cleanly. The Thermo Scientific portfolio includes over 5,000 organic synthesis reagents, including reducing and oxidizing reagents, organometallics, commonly used functional reagents, and specialty reagents for specific reactions.

Battery research and manufacturing

In the rapidly evolving world of battery technology, our chemicals portfolio supports the discovery and development of newer, next-generation battery technologies as well as the improvement of lithium-ion batteries by making them safer, more energy efficient, more environmentally friendly, and less dependent on hard-to-procure metals.

Small-molecule drug discovery

The small-molecule drug discovery process is long, expensive, and risky, with a failure rate estimated at 97%. Our Thermo Scientific Maybridge screening and fragment libraries can shorten this process—and improve its chance of success—by helping to identify or produce high-quality, hit-like, lead-like, and drug-like compounds.

Small-molecule target validation

Thermo Scientific chemical probes are selective small-molecule modulators of a protein’s function, designed to allow researchers to ask mechanistic and phenotypic questions about their molecular target in cell-based or animal research studies. These compounds help reduce the technical and biological risks of pursuing a pathway or target before incurring the time and expense of drug development and clinical trials.

Protecting from PFAS

PFAS (Per- and polyfluorinated alkyl substances), also known as the forever chemicals, are ubiquitous and persistent synthetic chemicals. Due to their chemical properties, PFAS are widely used in numerous household and industrial products. As PFAS can be toxic, there is an increasingly need to test for the presence of these compounds. Analyzing PFAS can be challenging due to the low levels of detection and the need for chemicals and consumables that are suitable for PFAS testing.


Named reactions in organic chemistry

Learn about the history, reaction mechanisms, and applications of organic chemistry reactions that are named after the chemists that discovered them. Includes videos, eBooks, supporting product links, and other resources.
