Tiamulin EP impurity H CAS CATO-C4X-221015

Description

Compared with other compounds in its class, the molecular weight of 625.81 g/mol gives Tiamulin EP impurity H distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Tiamulin EP impurity H (CAS CATO-C4X-221015), a pharmacopoeial impurity reference standard (molecular formula C32H51NO9S, MW 625.81 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Tiamulin EP impurity H (C32H51NO9S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 625.81 g/mol, it falls into the high-molecular-weight range. 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 H 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.
