(Z)-1-(1,3,3-Trimethylindolin-2-ylidene)propan-2-one CAS 74145-97-4

Description

Compared with other compounds in its class, the molecular weight of 673.88 g/mol gives (Z)-1-(1,3,3-Trimethylindolin-2-ylidene)propan-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(Z)-1-(1,3,3-Trimethylindolin-2-ylidene)propan-2-one (CAS 74145-97-4), molecular formula C18H10Br4O8 and molecular weight 673.88 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (Z)-1-(1,3,3-Trimethylindolin-2-ylidene)propan-2-one (C18H10Br4O8) is characterized by a flavonoid core, a hydroxyl group, an ether linkage, bromine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
