Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3S,4R,5S)-5-((S)-2,2,7,7-Tetramethyl-3,6-dioxa-2,7-disilaoctan-4-yl)-3,4-bis((trimethylsilyl)oxy)dihydrofuran-2(3H)-one.
(3S,4R,5S)-5-((S)-2,2,7,7-Tetramethyl-3,6-dioxa-2,7-disilaoctan-4-yl)-3,4-bis((trimethylsilyl)oxy)dihydrofuran-2(3H)-one (CAS 56298-43-2), molecular formula C18H42O6Si4 and molecular weight 466.86 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C18H42O6Si4, (3S,4R,5S)-5-((S)-2,2,7,7-Tetramethyl-3,6-dioxa-2,7-disilaoctan-4-yl)-3,4-bis((trimethylsilyl)oxy)dihydrofuran-2(3H)-one 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 466.86 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry.
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.
