Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (Z)-Methyl 7-(5-oxo-3-((triethylsilyl)-oxy)cyclopent-1-en-1-yl)hept-5-enoate.
(Z)-Methyl 7-(5-oxo-3-((triethylsilyl)-oxy)cyclopent-1-en-1-yl)hept-5-enoate (CAS 102494-28-0) is a high-purity analytical reference standard with the molecular formula C19H32O4Si and a molecular weight of 352.54 g/mol.
Based on its molecular formula C19H32O4Si, (Z)-Methyl 7-(5-oxo-3-((triethylsilyl)-oxy)cyclopent-1-en-1-yl)hept-5-enoate 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 352.54 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.
