Chemical Structure

tert-Butyldimethyl(4-nitrophenoxy)silane CAS 117635-44-6 chemical structure

Description

The occurrence of tert-Butyldimethyl(4-nitrophenoxy)silane 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.

tert-Butyldimethyl(4-nitrophenoxy)silane (CAS 117635-44-6) is a high-purity analytical reference standard with the molecular formula C12H19NO3Si and a molecular weight of 253.37 g/mol.

tert-Butyldimethyl(4-nitrophenoxy)silane (C12H19NO3Si) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, 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.

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

As a certified reference material (CRM), tert-Butyldimethyl(4-nitrophenoxy)silane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
