Chemical Structure

(1E,4E)-4-Methyl-1-(trimethylsilyl)hexa-1,4-dien-3-one CAS 81255-90-5 chemical structure

Description

The molecular framework of (1E,4E)-4-Methyl-1-(trimethylsilyl)hexa-1,4-dien-3-one (C10H18OSi) is characterized by a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

(1E,4E)-4-Methyl-1-(trimethylsilyl)hexa-1,4-dien-3-one (CAS 81255-90-5), molecular formula C10H18OSi and molecular weight 182.33 g/mol, is a CATO reference standard with documented purity and traceability.

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.

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.
