Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tiamulin EP Impurity C.
As a process- or degradation-related impurity, Tiamulin EP Impurity C (CAS 589-32-2, C12H28N2S2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to sulfur-containing functionality, Tiamulin EP Impurity C is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 264.49 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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 C 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.
