E40OE44A24 26570-48-9 8P0OYN7WS1 1IPG6LB9NM PEG-4 diacrylate PEG-7 diacrylate PEG-9 diacrylate Poly(oxy-1,2-ethanediyl), alpha-(1-oxo-2-propen-1-yl)-omega-((1-oxo-2-propen-1-yl)oxy)- Poly(oxy-1,2-ethanediyl), alpha-(1-oxo-2-propenyl)-omega-((1-oxo-2-propenyl)oxy)- UNII-8P0OYN7WS1 UNII-1IPG6LB9NM UNII-E40OE44A24 (C3H4O2C2H6O2) contains a carbohydrate-derived structure. 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.
