4-({[(4-chlorophenyl)methyl]amino}methylidene)-3-methyl-4,5-dihydro-1H-pyrazol-5-one CAS 338975-77-2

Description

Compared with other compounds in its class, the molecular weight of 249.70 g/mol gives 4-({[(4-chlorophenyl)methyl]amino}methylidene)-3-methyl-4,5-dihydro-1H-pyrazol-5-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-({[(4-chlorophenyl)methyl]amino}methylidene)-3-methyl-4,5-dihydro-1H-pyrazol-5-one (CAS 338975-77-2), a certified reference material (molecular formula C12H12ClN3O, MW 249.70 g/mol) for analytical method development and quality control.

4-({[(4-chlorophenyl)methyl]amino}methylidene)-3-methyl-4,5-dihydro-1H-pyrazol-5-one (C12H12ClN3O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

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.
