Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (R)-2-Amino-3-((tert-butyldimethylsilyl)oxy)-3-methylbutanoic acid (CAS 1473385-12-4), a certified reference material (molecular formula C11H25NO3Si, MW 247.41 g/mol) for analytical method development and quality control.
The molecular framework of (R)-2-Amino-3-((tert-butyldimethylsilyl)oxy)-3-methylbutanoic acid (C11H25NO3Si) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
CATO manufactures (R)-2-Amino-3-((tert-butyldimethylsilyl)oxy)-3-methylbutanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
