Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Benzenesulfonic acid, 4-ethenyl-, sodium salt , polymer with 2-propenenitrile.
Benzenesulfonic acid, 4-ethenyl-, sodium salt , polymer with 2-propenenitrile (CAS 25464-57-7), molecular formula C8H7O3SC3H3NNa and molecular weight 259.25 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Benzenesulfonic acid, 4-ethenyl-, sodium salt , polymer with 2-propenenitrile is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 259.25 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
