Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 159.23 g/mol gives 2,3,5-Trimethyl-1H-indole distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2,3,5-Trimethyl-1H-indole (CAS 21296-92-4), molecular formula C11H13N and molecular weight 159.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 2,3,5-Trimethyl-1H-indole (C11H13N) is characterized by a nitrogen-containing heterocyclic scaffold, 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. 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.
CATO manufactures 2,3,5-Trimethyl-1H-indole under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
