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.
11-Cyano-9,10-dihydro-9,10-ethanoanthracene-11-carboxylic acid (CAS 60722-02-3) is a high-purity analytical reference standard with the molecular formula C18H13NO2 and a molecular weight of 275.30 g/mol.
The molecular framework of 11-Cyano-9,10-dihydro-9,10-ethanoanthracene-11-carboxylic acid (C18H13NO2) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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.
