Description

The occurrence of 1-[3-(Trimethoxysilyl)propyl]urea 23843-64-3 Cholest-5-en-3beta-yl p-nitrobenzoate [10,13-Dimethyl-17-(6-methylheptan-2-yl)-2,3,4,7,8,9,11,12,14,15,16,17-dodecahydro-1H-cyclopenta[a]phenanthren-3-yl] 4-nitrobenzoate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 1-[3-(Trimethoxysilyl)propyl]urea 23843-64-3 Cholest-5-en-3beta-yl p-nitrobenzoate [10,13-Dimethyl-17-(6-methylheptan-2-yl)-2,3,4,7,8,9,11,12,14,15,16,17-dodecahydro-1H-cyclopenta[a]phenanthren-3-yl] 4-nitrobenzoate (CAS 23843-64-3), a certified reference material (molecular formula C7H18N2O4Si, MW 222.31 g/mol) for analytical method development and quality control.

1-[3-(Trimethoxysilyl)propyl]urea 23843-64-3 Cholest-5-en-3beta-yl p-nitrobenzoate [10,13-Dimethyl-17-(6-methylheptan-2-yl)-2,3,4,7,8,9,11,12,14,15,16,17-dodecahydro-1H-cyclopenta[a]phenanthren-3-yl] 4-nitrobenzoate (C7H18N2O4Si) contains an amino-acid-derived structure, an amide 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.
