Chemical Structure
Description
CATO supplies N2-(2-Hydroxyethyl)-N4-(p-tolyl)-L-asparagine (CAS 85476-52-4), a certified reference material (molecular formula C13H18N2O4, MW 266.29 g/mol) for analytical method development and quality control.
The molecular framework of N2-(2-Hydroxyethyl)-N4-(p-tolyl)-L-asparagine (C13H18N2O4) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures N2-(2-Hydroxyethyl)-N4-(p-tolyl)-L-asparagine 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.
