N'-[(1E)-[4-(Dimethylamino)phenyl]methylidene]-3-(1H-pyrrol-1-yl)thiophene-2-carbohydrazide CAS 478076-86-7

Description

N'-[(1E)-[4-(Dimethylamino)phenyl]methylidene]-3-(1H-pyrrol-1-yl)thiophene-2-carbohydrazide (CAS 478076-86-7) is a high-purity analytical reference standard with the molecular formula C18H18N4OS and a molecular weight of 338.43 g/mol.

N'-[(1E)-[4-(Dimethylamino)phenyl]methylidene]-3-(1H-pyrrol-1-yl)thiophene-2-carbohydrazide (C18H18N4OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.
