Our labeled active pharmaceutical ingredient (API) standards provide laboratories with precise and reliable tools for quantitative analysis. These standards, marked with isotopes such as deuterium or 13C, ensure accurate internal calibration and correct for matrix effects in complex samples. This leads to more consistent and reproducible results, essential for drug development and regulatory compliance. By using our labeled API standards,laboratories can enhance the accuracy of their analytical methods and streamline validation processes.
