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 Iron(II) acetyl-L-cysteinate dihydrate.
Iron(II) acetyl-L-cysteinate dihydrate (CAS 111056-17-8), molecular formula C5H8NO3SFeH2O and molecular weight 236.04 g/mol, is a CATO reference standard with documented purity and traceability.
Iron(II) acetyl-L-cysteinate dihydrate (C5H8NO3SFeH2O) contains a carbohydrate-derived structure, an amide group, a sulfone group. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Iron(II) acetyl-L-cysteinate dihydrate 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.
