Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ferric pyrophosphate citrate.
Ferric pyrophosphate citrate (CAS 1332-96-3) is a high-purity analytical reference standard with the molecular formula C6H4O7HO7P2FeNa and a molecular weight of 441.88 g/mol.
Based on its molecular formula C6H4O7HO7P2FeNa, Ferric pyrophosphate citrate contains a carbohydrate-derived structure, a phosphate ester group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 441.88 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Ferric pyrophosphate citrate 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.
