Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 191.66 g/mol gives 1-(2-Chlorobenzyl)-1H-pyrrole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1-(2-Chlorobenzyl)-1H-pyrrole (CAS 23694-46-4), molecular formula C11H10ClN and molecular weight 191.66 g/mol, is a CATO reference standard with documented purity and traceability.
1-(2-Chlorobenzyl)-1H-pyrrole (C11H10ClN) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, 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. 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.
