Chemical Structure

1-Methyl-1H-indole-5-carboximidamide CAS 71889-74-2 chemical structure

Description

The molecular framework of 1-Methyl-1H-indole-5-carboximidamide (C10H11N3) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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).

1-Methyl-1H-indole-5-carboximidamide (CAS 71889-74-2), molecular formula C10H11N3 and molecular weight 173.21 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), 1-Methyl-1H-indole-5-carboximidamide 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.
