3-Methyl-4-({[(pyridin-3-yl)methyl]amino}methylidene)-4,5-dihydro-1H-pyrazol-5-one CAS 338975-75-0

Description

3-Methyl-4-({[(pyridin-3-yl)methyl]amino}methylidene)-4,5-dihydro-1H-pyrazol-5-one (C11H12N4O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

3-Methyl-4-({[(pyridin-3-yl)methyl]amino}methylidene)-4,5-dihydro-1H-pyrazol-5-one (CAS 338975-75-0), molecular formula C11H12N4O and molecular weight 216.24 g/mol, is a CATO reference standard with documented purity and traceability.

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.

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.
