Chemical Structure
Description
The occurrence of 4-(3-Chlorobenzoyl)-1-methyl-1H-pyrrole-2-carbaldehyde is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-(3-Chlorobenzoyl)-1-methyl-1H-pyrrole-2-carbaldehyde (CAS 338978-14-6), a certified reference material (molecular formula C13H10ClNO2, MW 247.68 g/mol) for analytical method development and quality control.
The molecular framework of 4-(3-Chlorobenzoyl)-1-methyl-1H-pyrrole-2-carbaldehyde (C13H10ClNO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
