Chemical Structure
Description
Structurally, Tobramycin Impurity 13 HCl (C6H13NO5HCl) contains a carbohydrate-derived structure, an amide group, chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 0.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 215.63 g/mol, it falls into the medium-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
CATO supplies Tobramycin Impurity 13 HCl (CAS 19309-98-9 (free base)), a pharmacopoeial impurity reference standard (molecular formula C6H13NO5HCl, MW 215.63 g/mol) used for the identification and quantification of trace impurities in APIs.
This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
As a certified reference material (CRM), Tobramycin Impurity 13 HCl 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.
