Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(6,7-Dimethyl-2-oxo-2,3-dihydro-1H-indol-3-yl)-acetic acid 3067AF 915921-16-3 C12H13NO3 (CAS 915921-16-3) is a high-purity analytical reference standard with the molecular formula C12H13NO3 and a molecular weight of 219.24 g/mol.
The molecular framework of (6,7-Dimethyl-2-oxo-2,3-dihydro-1H-indol-3-yl)-acetic acid 3067AF 915921-16-3 C12H13NO3 (C12H13NO3) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), (6,7-Dimethyl-2-oxo-2,3-dihydro-1H-indol-3-yl)-acetic acid 3067AF 915921-16-3 C12H13NO3 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.
