Chemical Structure

S-acetyl-PEG4-Boc CAS 1818294-26-6 chemical structure

Description

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.

S-acetyl-PEG4-Boc (CAS 1818294-26-6), molecular formula C17H32O7S and molecular weight 380.50 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of S-acetyl-PEG4-Boc (C17H32O7S) is characterized by a sulfone group, 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.

As a certified reference material (CRM), S-acetyl-PEG4-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.
