5452-61-9 Ethyl (2E,4E)-3-methyl-5-(2,6,6-trimethylcyclohex-1-EN-1-YL)penta-2,4-dienoate ethyl (2E,4E)-3-methyl-5-(2,6,6-trimethylcyclohexen-1-yl)penta-2,4-dienoate CAS 5452-61-9 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 5452-61-9 Ethyl (2E,4E)-3-methyl-5-(2,6,6-trimethylcyclohex-1-EN-1-YL)penta-2,4-dienoate ethyl (2E,4E)-3-methyl-5-(2,6,6-trimethylcyclohexen-1-yl)penta-2,4-dienoate.

5452-61-9 Ethyl (2E,4E)-3-methyl-5-(2,6,6-trimethylcyclohex-1-EN-1-YL)penta-2,4-dienoate ethyl (2E,4E)-3-methyl-5-(2,6,6-trimethylcyclohexen-1-yl)penta-2,4-dienoate (CAS 5452-61-9), molecular formula C17H26O2 and molecular weight 262.39 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C17H26O2, 5452-61-9 Ethyl (2E,4E)-3-methyl-5-(2,6,6-trimethylcyclohex-1-EN-1-YL)penta-2,4-dienoate ethyl (2E,4E)-3-methyl-5-(2,6,6-trimethylcyclohexen-1-yl)penta-2,4-dienoate contains a steroid core, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 262.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

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.
