Chemical Structure
Description
t-Boc-Aminooxy-PEG7-bromide (CAS 2353410-15-6), molecular formula C21H42BrNO10 and molecular weight 548.46 g/mol, is a CATO reference standard with documented purity and traceability.
t-Boc-Aminooxy-PEG7-bromide (C21H42BrNO10) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution. 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.
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), t-Boc-Aminooxy-PEG7-bromide 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.
