Description
CATO supplies 3-(3,4-Dihydro-1H-carbazol-9(2H)-yl)-N'-(1-(furan-2-yl)ethylidene)propanehydrazide (CAS 612047-98-0), a certified reference material (molecular formula C21H23N3O2, MW 349.43 g/mol) for analytical method development and quality control.
Structurally, 3-(3,4-Dihydro-1H-carbazol-9(2H)-yl)-N'-(1-(furan-2-yl)ethylidene)propanehydrazide (C21H23N3O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 349.43 g/mol, it falls into the moderately-high-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
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.
