Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
2-(4-(2-Methoxyphenyl)piperazin-1-yl)acetohydrazide (CAS 204973-87-5), molecular formula C13H20N4O2 and molecular weight 264.32 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2-(4-(2-Methoxyphenyl)piperazin-1-yl)acetohydrazide (C13H20N4O2) 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.
