Chemical Structure
Description
2-Propenoic acid, polymer with 1,3-butadiene, ethenylbenzene and 2-propenenitrile (CAS 26568-80-9), molecular formula C8H8C3H4O2C4H6C3H3N and molecular weight 283.37 g/mol, is a CATO reference standard with documented purity and traceability.
2-Propenoic acid, polymer with 1,3-butadiene, ethenylbenzene and 2-propenenitrile (C8H8C3H4O2C4H6C3H3N) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
