Chemical Structure
Description
Boc-Aminooxy-PEG2-C2-amine (CAS 252378-69-1), molecular formula C11H24N2O5 and molecular weight 264.32 g/mol, is a CATO reference standard with documented purity and traceability.
Boc-Aminooxy-PEG2-C2-amine (C11H24N2O5) contains an amino-acid-derived structure, 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Boc-Aminooxy-PEG2-C2-amine 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.
