Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3-(6-Chloropyridazin-3-yl)-1H-indol-1-yl)(cyclohexyl)methanone.
(3-(6-Chloropyridazin-3-yl)-1H-indol-1-yl)(cyclohexyl)methanone (CAS 439093-77-3), molecular formula C19H18ClN3O and molecular weight 339.82 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3-(6-Chloropyridazin-3-yl)-1H-indol-1-yl)(cyclohexyl)methanone (C19H18ClN3O) is characterized by a steroid core, 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.
