Chemical Structure
Description
The molecular framework of 1,1,3,3-Tetramethyl-2,3-dihydro-1H-indene (C13H18) is characterized by an aromatic ring system. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
1,1,3,3-Tetramethyl-2,3-dihydro-1H-indene (CAS 4834-33-7), molecular formula C13H18 and molecular weight 174.28 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 1,1,3,3-Tetramethyl-2,3-dihydro-1H-indene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
