TERT-BUTYL 2,2,3,3,9,9,10,10-OCTAMETHYL-4,8-DIOXA-3,9-DISILAUNDECAN-6-YLCARBAMATE CAS 1951440-94-0 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.

TERT-BUTYL 2,2,3,3,9,9,10,10-OCTAMETHYL-4,8-DIOXA-3,9-DISILAUNDECAN-6-YLCARBAMATE (CAS 1951440-94-0) is a high-purity analytical reference standard with the molecular formula C20H45NO4Si2 and a molecular weight of 419.75 g/mol.

Structurally, TERT-BUTYL 2,2,3,3,9,9,10,10-OCTAMETHYL-4,8-DIOXA-3,9-DISILAUNDECAN-6-YLCARBAMATE (C20H45NO4Si2) contains an amide group, 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 419.75 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
