Chemical Structure
Description
The occurrence of 4-((3-Methyl-3H-diazirin-3-yl)methyl)-1,2-diphenylpyrazolidine-3,5-dione is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-((3-Methyl-3H-diazirin-3-yl)methyl)-1,2-diphenylpyrazolidine-3,5-dione (CAS 29301-73-3), a certified reference material (molecular formula C18H16N4O2, MW 320.35 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-((3-Methyl-3H-diazirin-3-yl)methyl)-1,2-diphenylpyrazolidine-3,5-dione is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 320.35 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.
As a certified reference material (CRM), 4-((3-Methyl-3H-diazirin-3-yl)methyl)-1,2-diphenylpyrazolidine-3,5-dione 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.
