Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Nonanedioic acid, polymer with hexanedioic acid and 4,4'-methylenebis[benzenamine].
Nonanedioic acid, polymer with hexanedioic acid and 4,4'-methylenebis[benzenamine] (CAS 66787-20-0) is a high-purity analytical reference standard with the molecular formula C13H14N2C9H16O4C6H10O4 and a molecular weight of 532.63 g/mol.
Nonanedioic acid, polymer with hexanedioic acid and 4,4'-methylenebis[benzenamine] (C13H14N2C9H16O4C6H10O4) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), Nonanedioic acid, polymer with hexanedioic acid and 4,4'-methylenebis[benzenamine] 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.
