Description
As a certified reference material (CRM), N-(4-Chlorobenzoyl)-2-[(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)oxy]acetohydrazide 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.
N-(4-Chlorobenzoyl)-2-[(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)oxy]acetohydrazide (CAS 339105-83-8), molecular formula C17H12ClN3O5 and molecular weight 373.75 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, N-(4-Chlorobenzoyl)-2-[(1,3-dioxo-1,3-dihydro-2H-isoindol-2-yl)oxy]acetohydrazide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 373.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
