Cefaclor-d5 (CAS 1426173-90-1)

Cefaclor-d5 is a deuterated form of cefaclor, where five hydrogen atoms have been replaced with deuterium. This isotopic substitution is used to enhance the chemical′s application in research, particularly within the fields of analytical and environmental chemistry. Deuterium, being a stable and non-radioactive isotope of hydrogen, does not alter the chemical structure of cefaclor significantly but provides distinct advantages for scientific analysis. In mass spectrometry, the introduction of deuterium increases the molecular weight slightly, allowing cefaclor-d5 to be distinguished from non-deuterated forms, which is essential for accurate tracing and quantification in complex mixtures. This property is particularly beneficial in studies focusing on the environmental distribution and degradation pathways of cefaclor, as it helps in understanding how this compound behaves under various environmental conditions. Researchers use cefaclor-d5 to develop and refine analytical methods, ensuring that they can detect and measure even trace amounts of cefaclor in environmental samples, such as groundwater or soil. It also serves as an internal standard in analytical procedures, which helps in achieving high precision and reliability in the results, crucial for investigating the persistence and ecological impacts of antibiotic residues in the environment.
