Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-Methyl-1-(2-(m-tolyloxy)ethyl)indoline-2,3-dione.
7-Methyl-1-(2-(m-tolyloxy)ethyl)indoline-2,3-dione (CAS 620932-11-8), molecular formula C18H17NO3 and molecular weight 295.33 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 7-Methyl-1-(2-(m-tolyloxy)ethyl)indoline-2,3-dione (C18H17NO3) is characterized by a steroid core, 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).
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), 7-Methyl-1-(2-(m-tolyloxy)ethyl)indoline-2,3-dione 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.
