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 Ethanone, 1-[(1S,3aR,4S,7aS)-4-[[(1,1-dimethylethyl)dimethylsilyl]oxy]octahydro-7a-methyl-1H-inden-1-yl]-.
CATO supplies Ethanone, 1-[(1S,3aR,4S,7aS)-4-[[(1,1-dimethylethyl)dimethylsilyl]oxy]octahydro-7a-methyl-1H-inden-1-yl]- (CAS 140659-43-4), a certified reference material (molecular formula C18H34O2Si, MW 310.55 g/mol) for analytical method development and quality control.
Based on its molecular formula C18H34O2Si, Ethanone, 1-[(1S,3aR,4S,7aS)-4-[[(1,1-dimethylethyl)dimethylsilyl]oxy]octahydro-7a-methyl-1H-inden-1-yl]- contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 310.55 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.
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.
CATO manufactures Ethanone, 1-[(1S,3aR,4S,7aS)-4-[[(1,1-dimethylethyl)dimethylsilyl]oxy]octahydro-7a-methyl-1H-inden-1-yl]- under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
