Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Amino-7-hydroxy-2-methyl-4H-chromen-4-one.
CATO supplies 3-Amino-7-hydroxy-2-methyl-4H-chromen-4-one (CAS 742008-52-2), a certified reference material (molecular formula C10H9NO3, MW 191.18 g/mol) for analytical method development and quality control.
The molecular framework of 3-Amino-7-hydroxy-2-methyl-4H-chromen-4-one (C10H9NO3) 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.
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 3-Amino-7-hydroxy-2-methyl-4H-chromen-4-one 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.
