29690-82-2 Formaldehyde, polymer with 2-(chloromethyl)oxirane and 2-methylphenol Formaldehyde, polymer with (chloromethyl)oxirane and 2-methylphenol o-Cresol, 1-chloro-2,3-epoxypropane, formaldehyde polymer o-Cresol, formaldehyde, epichlorohydrin polymer o-Cresol, polymer with 1-chloro-2,3-epoxypropane and formaldehyde Epichlorohydrin, o-cresol, formaldehyde polymer (CAS 29690-82-2), molecular formula C7H8OC3H5ClOCH2O and molecular weight 230.69 g/mol, is a CATO reference standard with documented purity and traceability.

29690-82-2 Formaldehyde, polymer with 2-(chloromethyl)oxirane and 2-methylphenol Formaldehyde, polymer with (chloromethyl)oxirane and 2-methylphenol o-Cresol, 1-chloro-2,3-epoxypropane, formaldehyde polymer o-Cresol, formaldehyde, epichlorohydrin polymer o-Cresol, polymer with 1-chloro-2,3-epoxypropane and formaldehyde Epichlorohydrin, o-cresol, formaldehyde polymer (C7H8OC3H5ClOCH2O) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. It is notably hygroscopic, halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
