Chemical Structure
Description
The occurrence of Cys1-Linaclotide Imidazolidione Impurity XTFA Salt is closely related to a structurally diverse molecular composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Cys1-Linaclotide Imidazolidione Impurity XTFA Salt (CAS CATO-C4X-21061), a pharmacopoeial impurity reference standard (molecular formula N/A, MW N/A g/mol) used for the identification and quantification of trace impurities in APIs.
Cys1-Linaclotide Imidazolidione Impurity XTFA Salt is supplied as a fully characterized reference material; its structural identity, assigned purity, and stability data are documented in the batch-specific Certificate of Analysis (COA).
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), Cys1-Linaclotide Imidazolidione Impurity XTFA Salt 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.
