Chemical Structure

26009-55-2 poly(4-t-butyl styrene) CAS 26009-55-2 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.

26009-55-2 poly(4-t-butyl styrene) (CAS 26009-55-2), molecular formula C12H22 and molecular weight 166.30 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an organic framework, 26009-55-2 poly(4-t-butyl styrene) is typically white to off-white low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 166.30 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
