Chemical Structure

7-Methyl-1H-indol-4-ol CAS 19499-91-3 chemical structure

Description

As a certified reference material (CRM), 7-Methyl-1H-indol-4-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.

7-Methyl-1H-indol-4-ol (CAS 19499-91-3), molecular formula C9H9NO and molecular weight 147.17 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 7-Methyl-1H-indol-4-ol (C9H9NO) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, 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.
