Description
CATO manufactures 2-Propenoic acid, 2-methyl-, polymer with 1,3-butadiene, 1,1-dichloroethene and ethenylbenzene under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
CATO supplies 2-Propenoic acid, 2-methyl-, polymer with 1,3-butadiene, 1,1-dichloroethene and ethenylbenzene (CAS 26249-26-3), a certified reference material (molecular formula C8H8C2H2Cl2C4H6O2C4H6, MW 341.27 g/mol) for analytical method development and quality control.
2-Propenoic acid, 2-methyl-, polymer with 1,3-butadiene, 1,1-dichloroethene and ethenylbenzene (C8H8C2H2Cl2C4H6O2C4H6) contains a steroid core, a hydroxyl group, an ether linkage, chlorine substitution. 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.
