(R)-1-((tert-Butyldimethylsilyl)oxy)-3-(octadecyloxy)propan-2-ol (CAS 866784-45-4), molecular formula C27H58O3Si and molecular weight 458.83 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (R)-1-((tert-Butyldimethylsilyl)oxy)-3-(octadecyloxy)propan-2-ol (C27H58O3Si) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -1.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 458.83 g/mol, it falls into the moderately-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.
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.
