Chemical Structure
Description
The occurrence of Hydroxy-PEG24-Boc is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Hydroxy-PEG24-Boc (CAS 2490419-62-8) is a high-purity analytical reference standard with the molecular formula C55H110O27 and a molecular weight of 1203.45 g/mol.
The molecular framework of Hydroxy-PEG24-Boc (C55H110O27) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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), Hydroxy-PEG24-Boc 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.
