Chemical Structure
Description
The occurrence of 3-Chloro-1-(1,3,3-trimethyl-2,3-dihydro-1h-indol-2-ylidene)butan-2-one 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 3-Chloro-1-(1,3,3-trimethyl-2,3-dihydro-1h-indol-2-ylidene)butan-2-one (CAS 924873-02-9), a certified reference material (molecular formula C15H18ClNO, MW 263.76 g/mol) for analytical method development and quality control.
The molecular framework of 3-Chloro-1-(1,3,3-trimethyl-2,3-dihydro-1h-indol-2-ylidene)butan-2-one (C15H18ClNO) 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
