60665-85-2 2,4,6,8-Tetramethyl-2,4,6,8-tetrakis(3-(oxiranylmethoxy)propyl)cyclotetrasiloxane EINECS 262-360-7 (CAS 60665-85-2), molecular formula C28H56O12Si4 and molecular weight 697.08 g/mol, is a CATO reference standard with documented purity and traceability.
60665-85-2 2,4,6,8-Tetramethyl-2,4,6,8-tetrakis(3-(oxiranylmethoxy)propyl)cyclotetrasiloxane EINECS 262-360-7 (C28H56O12Si4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. 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.
