(2E,5E)-2,5-Bis(2-((E)-1,3,3-trimethylindolin-2-ylidene)ethylidene)cyclopentan-1-one CAS 27713-85-5

Description

The occurrence of (2E,5E)-2,5-Bis(2-((E)-1,3,3-trimethylindolin-2-ylidene)ethylidene)cyclopentan-1-one is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (2E,5E)-2,5-Bis(2-((E)-1,3,3-trimethylindolin-2-ylidene)ethylidene)cyclopentan-1-one (CAS 27713-85-5), a certified reference material (molecular formula C31H34N2O, MW 450.61 g/mol) for analytical method development and quality control.

(2E,5E)-2,5-Bis(2-((E)-1,3,3-trimethylindolin-2-ylidene)ethylidene)cyclopentan-1-one (C31H34N2O) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
