Chemical Structure
Description
Dde Biotin-PEG4-alkyne (CAS 1802908-00-4), molecular formula C32H50N4O8S and molecular weight 650.83 g/mol, is a CATO reference standard with documented purity and traceability.
Dde Biotin-PEG4-alkyne (C32H50N4O8S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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).
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.
As a certified reference material (CRM), Dde Biotin-PEG4-alkyne 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.
