Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Butanedioic acid, 2-methylene-, polymer with butyl 2-propenoate, ethenylbenzene and 2-hydroxyethyl 2-methyl-2-propenoate.
CATO supplies Butanedioic acid, 2-methylene-, polymer with butyl 2-propenoate, ethenylbenzene and 2-hydroxyethyl 2-methyl-2-propenoate (CAS 25119-70-4), a certified reference material (molecular formula C6H10O3C5H6O4C7H12O2C8H8, MW 492.56 g/mol) for analytical method development and quality control.
Butanedioic acid, 2-methylene-, polymer with butyl 2-propenoate, ethenylbenzene and 2-hydroxyethyl 2-methyl-2-propenoate (C6H10O3C5H6O4C7H12O2C8H8) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
