Chemical Structure
Description
6-(((tert-Butyldiphenylsilyl)oxy)methyl)tetrahydro-2H-pyran-3-carboxylic acid (CAS 2758411-39-9), molecular formula C23H30O4Si and molecular weight 398.57 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 6-(((tert-Butyldiphenylsilyl)oxy)methyl)tetrahydro-2H-pyran-3-carboxylic acid (C23H30O4Si) contains a flavonoid core, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 398.57 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
