Chemical Structure
Description
1-Acetyl-2,3-dihydro-2-methyl-1H-indol-5-ol (CAS 186792-92-7), molecular formula C11H13NO2 and molecular weight 191.23 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 1-Acetyl-2,3-dihydro-2-methyl-1H-indol-5-ol (C11H13NO2) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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.
As a certified reference material (CRM), 1-Acetyl-2,3-dihydro-2-methyl-1H-indol-5-ol 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.
