Description

1-[3-(2-Aminoethyl)amino]propyl-3,5,7,9,11,13,15-isobutylpentacyclo[9.5.1.1(3,9).1(5,15).1(7,13)]octasiloxane 444315-16-6 Aminoethylaminopropylisobutyl-POSS® POSS®-Aminoethylaminopropyl-isobutyl substituted PSS-[3-(2-Aminoethyl)amino]propyl-Heptaisobutyl substituted (CAS 444315-16-6), molecular formula C33H76N2O12Si8 and molecular weight 917.65 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C33H76N2O12Si8, 1-[3-(2-Aminoethyl)amino]propyl-3,5,7,9,11,13,15-isobutylpentacyclo[9.5.1.1(3,9).1(5,15).1(7,13)]octasiloxane 444315-16-6 Aminoethylaminopropylisobutyl-POSS® POSS®-Aminoethylaminopropyl-isobutyl substituted PSS-[3-(2-Aminoethyl)amino]propyl-Heptaisobutyl substituted contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 917.65 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
