Chemical Structure
Description
(1R,3R,4S)-4-((tert-Butyldiphenylsilyl)oxy)-2-methylene-3-((trityloxy)methyl)cyclopentanol (CAS 1233193-58-2) is a high-purity analytical reference standard with the molecular formula C42H44O3Si and a molecular weight of 624.88 g/mol.
Structurally, (1R,3R,4S)-4-((tert-Butyldiphenylsilyl)oxy)-2-methylene-3-((trityloxy)methyl)cyclopentanol (C42H44O3Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 21.0, corresponding to approximately 21 ring(s) or double-bond equivalent(s). With a molecular weight of 624.88 g/mol, it falls into the high-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.
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.
