2-Propenoic acid, 2-methyl-, polymer with 2-(chloromethyl)oxirane, ethenylbenzene and 4,4'-(1-methylethylidene)bis[phenol] (CAS 28262-39-7), molecular formula C15H16O2C8H8C3H5ClOC4H6O2 and molecular weight 511.06 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a steroid core, a hydroxyl group, an ether linkage, chlorine substitution, 2-Propenoic acid, 2-methyl-, polymer with 2-(chloromethyl)oxirane, ethenylbenzene and 4,4'-(1-methylethylidene)bis[phenol] is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 511.06 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
