Chemical Structure
Description
As a certified reference material (CRM), 1-Methyl-4,7-dihydro-1H-indole 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.
1-Methyl-4,7-dihydro-1H-indole (CAS 98995-73-4), molecular formula C9H11N and molecular weight 133.19 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-Methyl-4,7-dihydro-1H-indole (C9H11N) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 133.19 g/mol, it falls into the low-molecular-weight range. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
