Chemical Structure
Description
5-(1-Amino-2-hydroxyethyl)-2-methoxyphenol (CAS 1179669-77-2), molecular formula C9H13NO3 and molecular weight 183.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-(1-Amino-2-hydroxyethyl)-2-methoxyphenol (C9H13NO3) 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 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.
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.
CATO manufactures 5-(1-Amino-2-hydroxyethyl)-2-methoxyphenol 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.
