2,2,3,3,9,9,10,10-Octamethyl-4,8-dioxa-3,9-disilaundecane CAS 82112-22-9 chemical structure

Description

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.

2,2,3,3,9,9,10,10-Octamethyl-4,8-dioxa-3,9-disilaundecane (CAS 82112-22-9), molecular formula C15H36O2Si2 and molecular weight 304.62 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 2,2,3,3,9,9,10,10-Octamethyl-4,8-dioxa-3,9-disilaundecane (C15H36O2Si2) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of -2.0, corresponding to approximately 0 ring(s) or double-bond equivalent(s). With a molecular weight of 304.62 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.
