Compared with other compounds in its class, the molecular weight of 222.28 g/mol gives m-PEG4-CH2-alcohol distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
m-PEG4-CH2-alcohol (CAS 145526-76-7), molecular formula C10H22O5 and molecular weight 222.28 g/mol, is a CATO reference standard with documented purity and traceability.
m-PEG4-CH2-alcohol (C10H22O5) contains a carboxylic acid 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.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
