Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (3aR,4R,5R,6aS)-5-((tert-Butyldimethylsilyl)oxy)-2-oxohexahydro-2H-cyclopenta[b]furan-4-carbaldehyde (CAS 64091-14-1), a certified reference material (molecular formula C14H24O4Si, MW 284.42 g/mol) for analytical method development and quality control.
Structurally, (3aR,4R,5R,6aS)-5-((tert-Butyldimethylsilyl)oxy)-2-oxohexahydro-2H-cyclopenta[b]furan-4-carbaldehyde (C14H24O4Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 284.42 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
