Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Benzene, ethenyl-, polymer with ethene.
Benzene, ethenyl-, polymer with ethene (CAS 25068-12-6) is a high-purity analytical reference standard with the molecular formula C8H8C2H4 and a molecular weight of 132.21 g/mol.
Owing to an aromatic ring system, Benzene, ethenyl-, polymer with ethene is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 132.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
