BOC Sciences is committed to providing customers with isotope-labeled APIs. We offer a complete range of labeled APIs standards. We offer stock or custom API standards that can be used as internal standards. All products come with comprehensive analytical data files and are of high chemical purity.

What are APIs?

API, also known as active pharmaceutical ingredient, refers to any substance or mixture of substances used in the manufacture of pharmaceuticals. This substance becomes an active ingredient of medicines when it is used in medicine and cannot be taken directly by patients. Generally speaking, after adding excipients and processing, API can be made into medicines that can be used directly. APIs are usually prepared by chemical synthesis, plant extraction or biotechnology. APIs have pharmacological activity or other direct effects in the diagnosis, treatment and prevention of disease. API can also affect the function or structure of the organism. Drugs rely on tightly controlled APIs. Many medicines combine multiple active ingredients. Interactions between active ingredients can affect the function of the drug. The research methods and technologies of APIs include chiral technology, combinatorial chemistry, cell and molecular biology, protein engineering, genetic engineering, computer-aided drug design, etc. Applications for APIs include oncology, diabetes, cardiovascular disease, central nervous system and neurological disorders, endocrinology, and more.

Isotope-Labeled APIs

Isotope-labeled API is a chemical reagent that contains one or several isotopic atoms in the molecule, and uses its traceability for analytical determination. The chemical properties of the reagents replaced by isotopes are usually unchanged except for isotopic effects. Therefore, isotope-labeled reagents can participate in similar chemical reactions and are widely used as tracers to study the laws of substance movement and change.
