Compared with other compounds in its class, the molecular weight of 575.04 g/mol gives Formic acid, methyl ester, polymer with N1-[3-(dimethoxymethylsilyl)propyl]-1,2-ethanediamine and 2,2,4,4,6,6,8,8-octamethylcyclotetrasiloxane distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Formic acid, methyl ester, polymer with N1-[3-(dimethoxymethylsilyl)propyl]-1,2-ethanediamine and 2,2,4,4,6,6,8,8-octamethylcyclotetrasiloxane (CAS 168811-63-0), a certified reference material (molecular formula C8H24O4Si4C9H22N2O2SiC2H4O2, MW 575.04 g/mol) for analytical method development and quality control.
Formic acid, methyl ester, polymer with N1-[3-(dimethoxymethylsilyl)propyl]-1,2-ethanediamine and 2,2,4,4,6,6,8,8-octamethylcyclotetrasiloxane (C8H24O4Si4C9H22N2O2SiC2H4O2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
