Chemical Structure
Description
As a certified reference material (CRM), 6-tert-Butyl-1H-indole-2-carboxylic acid 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.
6-tert-Butyl-1H-indole-2-carboxylic acid (CAS 383133-22-0), molecular formula C13H15NO2 and molecular weight 217.26 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 6-tert-Butyl-1H-indole-2-carboxylic acid (C13H15NO2) 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 its high hydrophobicity (logP), 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.
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.
