Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 180.20 g/mol gives 2-(3-Methoxyphenyl)ethanohydrazide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-(3-Methoxyphenyl)ethanohydrazide (CAS 34624-38-9), molecular formula C9H12N2O2 and molecular weight 180.20 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(3-Methoxyphenyl)ethanohydrazide (C9H12N2O2) 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.
CATO manufactures 2-(3-Methoxyphenyl)ethanohydrazide 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.
