Structurally, (S)-4-(4-((tert-Butyldimethylsilyl)oxy)butan-2-yl)-2-isopropylpyridin-3-amine (C18H34N2OSi) contains an amide 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 322.56 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.
(S)-4-(4-((tert-Butyldimethylsilyl)oxy)butan-2-yl)-2-isopropylpyridin-3-amine (CAS 2641028-32-0), molecular formula C18H34N2OSi and molecular weight 322.56 g/mol, is a CATO reference standard with documented purity and traceability.
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.
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.
