Chemical Structure
Description
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.
CATO supplies Benzene, 1-ethenyl-4-methyl-, polymer with 2-methyl-1-propene (CAS 61128-14-1), a certified reference material (molecular formula C9H10C4H8, MW 174.29 g/mol) for analytical method development and quality control.
Structurally, Benzene, 1-ethenyl-4-methyl-, polymer with 2-methyl-1-propene (C9H10C4H8) contains an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 174.29 g/mol, it falls into the medium-molecular-weight range. 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.
