Chemical Structure

N-Methyl-6-hydroxy-2-oxyindole CAS 13383-73-8 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

N-Methyl-6-hydroxy-2-oxyindole (CAS 13383-73-8), molecular formula C9H9NO2 and molecular weight 163.17 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, N-Methyl-6-hydroxy-2-oxyindole is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 163.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

As a certified reference material (CRM), N-Methyl-6-hydroxy-2-oxyindole 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.
