Chemical Structure
Description
The occurrence of 7-Methyl-1,2,3,4-tetrahydrocyclopenta[b]indole-2-carboxylic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 7-Methyl-1,2,3,4-tetrahydrocyclopenta[b]indole-2-carboxylic acid (CAS 62645-83-4), a certified reference material (molecular formula C13H13NO2, MW 215.25 g/mol) for analytical method development and quality control.
Based on its molecular formula C13H13NO2, 7-Methyl-1,2,3,4-tetrahydrocyclopenta[b]indole-2-carboxylic acid contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 215.25 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
CATO manufactures 7-Methyl-1,2,3,4-tetrahydrocyclopenta[b]indole-2-carboxylic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
