Thiamine EP Impurity F CAS 10593-44-9

Description

Compared with other compounds in its class, the molecular weight of 279.38 g/mol gives Thiamine EP Impurity F distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Thiamine EP Impurity F (CAS 10593-44-9), a pharmacopoeial impurity reference standard (molecular formula C13H19BrN4OS, MW 279.38 g/mol) used for the identification and quantification of trace impurities in APIs.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, bromine substitution, Thiamine EP Impurity F is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 279.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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), Thiamine EP Impurity F 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.
