Displaying 2 results of Benzocaine Stable Isotopes Benzocaine stable isotopes are a set of non-radioactive isotopes of the local anesthetic benzocaine. These isotopes have the same chemical properties as normal benzocaine but have a different number of neutrons in their atomic nuclei. Benzocaine stable isotopes are used in research and medical applications, such as studying the metabolism and distribution of benzocaine in the body. They are also used as internal standards in analytical chemistry to improve accuracy and precision in measurements.
