Chemical Structure
Description
The occurrence of 3-(2,6,6-Trimethyl-4-oxo-4,5,6,7-tetrahydro-1H-indol-1-yl)propanoic 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.
3-(2,6,6-Trimethyl-4-oxo-4,5,6,7-tetrahydro-1H-indol-1-yl)propanoic acid (CAS 937605-34-0), molecular formula C14H19NO3 and molecular weight 249.31 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, 3-(2,6,6-Trimethyl-4-oxo-4,5,6,7-tetrahydro-1H-indol-1-yl)propanoic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 249.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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 3-(2,6,6-Trimethyl-4-oxo-4,5,6,7-tetrahydro-1H-indol-1-yl)propanoic 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.
