Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including n'-((9-Ethyl-9h-carbazol-3-yl)methylene)-3-(4-methylpiperazin-1-yl)propanehydrazide.

n'-((9-Ethyl-9h-carbazol-3-yl)methylene)-3-(4-methylpiperazin-1-yl)propanehydrazide (CAS 303227-64-7) is a high-purity analytical reference standard with the molecular formula C23H29N5O and a molecular weight of 391.51 g/mol.

Structurally, n'-((9-Ethyl-9h-carbazol-3-yl)methylene)-3-(4-methylpiperazin-1-yl)propanehydrazide (C23H29N5O) 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 391.51 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
