4792-67-0 5-chloroindole-2-carboxylicacidethylester A7316 ethyl 5-chloro-1H-indole-2-carboxylate CAS 4792-67-0 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 231.72 g/mol gives 4792-67-0 5-chloroindole-2-carboxylicacidethylester A7316 ethyl 5-chloro-1H-indole-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

4792-67-0 5-chloroindole-2-carboxylicacidethylester A7316 ethyl 5-chloro-1H-indole-2-carboxylate (CAS 4792-67-0), molecular formula C11H18ClNO2 and molecular weight 231.72 g/mol, is a CATO reference standard with documented purity and traceability.

4792-67-0 5-chloroindole-2-carboxylicacidethylester A7316 ethyl 5-chloro-1H-indole-2-carboxylate (C11H18ClNO2) contains an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. Halogen substitution raises its density and boiling point, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 4792-67-0 5-chloroindole-2-carboxylicacidethylester A7316 ethyl 5-chloro-1H-indole-2-carboxylate 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.
