Since 1975 MB has been engaged in the manufacture of radiochemicals and unlabeled compounds to support the needs of the scientific research community, providing compounds in demand and unavailable from other sources. We also offer many non-exclusive compounds at exceptionally high purity, and at substantially lower than other competitors' list prices. Today, after two decades of consistent growth and commitment to the field of radiolabeled compounds, MB presents a catalog of more than seven hundred tritium [3H] and carbon-14 [14C] labeled products. MB's expanded staff, refined facilities, and extensive and frequent use of HPLC purification and analysis result in the highest quality standard in the radiochemical industry. Our experienced team of radiochemists is ready to provide support for orders and inquiries. Whether you are interested in a catalog item or a complex custom synthesis our staff's goal is prompt and courteous service. We look forward to being of assitance to you in your research this year, and as always your suggestions for additions to our product line or ways to improve service are welcome.
