Chemical Structure
Description
1-(5-Chloro-2-methylphenyl)-2,5-dimethyl-1h-pyrrole-3-carbaldehyde (CAS 428466-65-3) is a high-purity analytical reference standard with the molecular formula C14H14ClNO and a molecular weight of 247.72 g/mol.
1-(5-Chloro-2-methylphenyl)-2,5-dimethyl-1h-pyrrole-3-carbaldehyde (C14H14ClNO) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
