Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 1-(2-Nitrobenzyl)-1H-pyrrole-2-carbaldehyde.
1-(2-Nitrobenzyl)-1H-pyrrole-2-carbaldehyde (CAS 22162-51-2) is a high-purity analytical reference standard with the molecular formula C12H10N2O3 and a molecular weight of 230.22 g/mol.
1-(2-Nitrobenzyl)-1H-pyrrole-2-carbaldehyde (C12H10N2O3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
