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 N-(m-PEG9)-N'-(propargyl-PEG8)-Cy5.
N-(m-PEG9)-N'-(propargyl-PEG8)-Cy5 (CAS 2107273-10-7) is a high-purity analytical reference standard with the molecular formula C63H99N2O17Cl and a molecular weight of 1191.93 g/mol.
N-(m-PEG9)-N'-(propargyl-PEG8)-Cy5 (C63H99N2O17Cl) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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), N-(m-PEG9)-N'-(propargyl-PEG8)-Cy5 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.
