Chemical Structure
Description
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.
2,5-Dimethyl-1-[1-(propan-2-yl)-1h-pyrazol-5-yl]-1h-pyrrole-3-carbaldehyde (CAS 956386-28-0) is a high-purity analytical reference standard with the molecular formula C13H17N3O and a molecular weight of 231.29 g/mol.
The molecular framework of 2,5-Dimethyl-1-[1-(propan-2-yl)-1h-pyrazol-5-yl]-1h-pyrrole-3-carbaldehyde (C13H17N3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), 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).
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.
