Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including m-PEG3-S-PEG2-OH.
m-PEG3-S-PEG2-OH (CAS 2173095-09-3), molecular formula C13H28O6S and molecular weight 312.42 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of m-PEG3-S-PEG2-OH (C13H28O6S) 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.
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), m-PEG3-S-PEG2-OH 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.
