Tiamulin EP Impurity R CAS 54225-72-8 chemical structure

Description

Tiamulin EP Impurity R (CAS 54225-72-8) is a certified pharmaceutical impurity reference standard with the molecular formula C19H34N and a molecular weight of 276.48 g/mol.

Based on its molecular formula C19H34N, Tiamulin EP Impurity R contains a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 276.48 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.

As a certified reference material (CRM), Tiamulin EP Impurity R meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
