Description
CATO manufactures Indole-2,4,5,6,7-d5-3-acetic 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.
Indole-2,4,5,6,7-d5-3-acetic Acid (CAS 76937-78-5), molecular formula C10H4D5NO2 and molecular weight 180.21 g/mol, is a CATO reference standard with documented purity and traceability.
Indole-2,4,5,6,7-d5-3-acetic Acid (C10H4D5NO2) contains deuterium isotope labeling, an amino-acid-derived structure, 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. 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.
