Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-[[4-(3,5-Dimethyl-1H-Pyrazol-1-yl-1-Phthalazinyl]Thio]-N-(4-Fluorophenyl)-Acetamide.
CATO supplies 2-[[4-(3,5-Dimethyl-1H-Pyrazol-1-yl-1-Phthalazinyl]Thio]-N-(4-Fluorophenyl)-Acetamide (CAS 606122-31-0), a certified reference material (molecular formula C21H18FN5OS, MW 407.46 g/mol) for analytical method development and quality control.
Structurally, 2-[[4-(3,5-Dimethyl-1H-Pyrazol-1-yl-1-Phthalazinyl]Thio]-N-(4-Fluorophenyl)-Acetamide (C21H18FN5OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 407.46 g/mol, it falls into the moderately-high-molecular-weight range. 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), 2-[[4-(3,5-Dimethyl-1H-Pyrazol-1-yl-1-Phthalazinyl]Thio]-N-(4-Fluorophenyl)-Acetamide 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.
