Description
CATO manufactures Methyl 3-Amino-4-hydroxybenzoate 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.
CATO supplies Methyl 3-Amino-4-hydroxybenzoate (CAS 536-25-4), a certified reference material (molecular formula C8H9NO3, MW 167.16 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 3-Amino-4-hydroxybenzoate (C8H9NO3) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
