Chemical Structure
Description
The occurrence of Propargyl-PEG2-urea-C3-triethoxysilane is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Propargyl-PEG2-urea-C3-triethoxysilane (CAS 1637329-79-3), a certified reference material (molecular formula C17H34N2O6Si, MW 390.55 g/mol) for analytical method development and quality control.
Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, Propargyl-PEG2-urea-C3-triethoxysilane is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 390.55 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
