6-(Indolin-1-yl)-5-methylnicotinic acid CAS 1355189-96-6

Description

The occurrence of 6-(Indolin-1-yl)-5-methylnicotinic 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.

6-(Indolin-1-yl)-5-methylnicotinic acid (CAS 1355189-96-6), molecular formula C15H14N2O2 and molecular weight 254.28 g/mol, is a CATO reference standard with documented purity and traceability.

6-(Indolin-1-yl)-5-methylnicotinic acid (C15H14N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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 6-(Indolin-1-yl)-5-methylnicotinic 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.
