Chemical Structure
Description
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.
Folic Acid Impurity 48 (CAS CATO-C4X-139548) is a certified pharmaceutical impurity reference standard with the molecular formula C19H19N7O6 and a molecular weight of 441.40 g/mol.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, Folic Acid Impurity 48 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 441.40 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Folic Acid Impurity 48 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.
