Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Benzene, ethenylmethyl-, homopolymer.
CATO supplies Benzene, ethenylmethyl-, homopolymer (CAS 9017-21-4), a certified reference material (molecular formula C9H10, MW 118.18 g/mol) for analytical method development and quality control.
Owing to an aromatic ring system, Benzene, ethenylmethyl-, homopolymer is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 118.18 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
