Chemical Structure
Description
The occurrence of Furazolidone Impurity 12 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Furazolidone Impurity 12 (CAS 13743-07-2), a pharmacopoeial impurity reference standard (molecular formula C3H7N3O3, MW 133.11 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, Furazolidone Impurity 12 is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 133.11 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.
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), Furazolidone Impurity 12 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.
