Chemical Structure
Description
The molecular framework of 3-(1H-pyrrol-1-yl)thiophene-2-carbohydrazide (C9H9N3OS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
CATO supplies 3-(1H-pyrrol-1-yl)thiophene-2-carbohydrazide (CAS 478050-34-9), a certified reference material (molecular formula C9H9N3OS, MW 207.25 g/mol) for analytical method development and quality control.
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.
