Chemical Structure
Description
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.
6-Bromo-2,3-dihydro-1h-cyclopenta[b]quinoline-9-carboxylic acid (CAS 923740-00-5) is a high-purity analytical reference standard with the molecular formula C13H10BrNO2 and a molecular weight of 292.13 g/mol.
The molecular framework of 6-Bromo-2,3-dihydro-1h-cyclopenta[b]quinoline-9-carboxylic acid (C13H10BrNO2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, bromine 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.
