Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-Methyl-5-phenyl-1H-indole-2-carboxylic acid.
3-Methyl-5-phenyl-1H-indole-2-carboxylic acid (CAS 191868-97-0) is a high-purity analytical reference standard with the molecular formula C16H13NO2 and a molecular weight of 251.28 g/mol.
3-Methyl-5-phenyl-1H-indole-2-carboxylic acid (C16H13NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
