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.
3-(3-Methoxy-4-((4-methylbenzyl)oxy)phenyl)-N'-((2-methyl-1H-indol-3-yl)methylene)-1H-pyrazole-5-carbohydrazide (CAS 1285684-25-4), molecular formula C29H27N5O3 and molecular weight 493.56 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 3-(3-Methoxy-4-((4-methylbenzyl)oxy)phenyl)-N'-((2-methyl-1H-indol-3-yl)methylene)-1H-pyrazole-5-carbohydrazide (C29H27N5O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 19.0, corresponding to approximately 19 ring(s) or double-bond equivalent(s). With a molecular weight of 493.56 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).
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.
