Diethyl ((4-chloro-2-methyl-5-oxo-1-phenyl-2,5-dihydro-1H-pyrazol-3-yl)methyl)phosphonate CAS 1020252-43-0

Description

As a certified reference material (CRM), Diethyl ((4-chloro-2-methyl-5-oxo-1-phenyl-2,5-dihydro-1H-pyrazol-3-yl)methyl)phosphonate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

CATO supplies Diethyl ((4-chloro-2-methyl-5-oxo-1-phenyl-2,5-dihydro-1H-pyrazol-3-yl)methyl)phosphonate (CAS 1020252-43-0), a certified reference material (molecular formula C15H20ClN2O4P, MW 358.76 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a phosphate ester group, a hydroxyl group, an ether linkage, chlorine substitution, Diethyl ((4-chloro-2-methyl-5-oxo-1-phenyl-2,5-dihydro-1H-pyrazol-3-yl)methyl)phosphonate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 358.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
