Description
Compared with other compounds in its class, the molecular weight of 153.26 g/mol gives 1h-indole, 2,3-dimethyl- 2,3-Dimethyl-indol 2,3-dimethyl-1h-indol 2,3-dimethyl-1h-indole 2,3-dimethyl-indole 2,3-dimethylindole 2,3-dimethylindole, 97+% 2,3-dimethylindoline 91-55-4 indole, 2,3-dimethyl- distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
1h-indole, 2,3-dimethyl- 2,3-Dimethyl-indol 2,3-dimethyl-1h-indol 2,3-dimethyl-1h-indole 2,3-dimethyl-indole 2,3-dimethylindole 2,3-dimethylindole, 97+% 2,3-dimethylindoline 91-55-4 indole, 2,3-dimethyl- (CAS 91-55-4), molecular formula C10H19N and molecular weight 153.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1h-indole, 2,3-dimethyl- 2,3-Dimethyl-indol 2,3-dimethyl-1h-indol 2,3-dimethyl-1h-indole 2,3-dimethyl-indole 2,3-dimethylindole 2,3-dimethylindole, 97+% 2,3-dimethylindoline 91-55-4 indole, 2,3-dimethyl- (C10H19N) is characterized by a nitrile group. 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.
