Description
CATO manufactures N-(m-PEG4)-N'-(DBCO-PEG4)-Cy5 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
N-(m-PEG4)-N'-(DBCO-PEG4)-Cy5 (CAS 2107273-76-5), molecular formula C63H79N4O10Cl and molecular weight 1087.79 g/mol, is a CATO reference standard with documented purity and traceability.
N-(m-PEG4)-N'-(DBCO-PEG4)-Cy5 (C63H79N4O10Cl) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
