Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Ethyl 4-chloro-5-formyl-3-methyl-6,7-dihydro-1H-indole-2-carboxylate.
Ethyl 4-chloro-5-formyl-3-methyl-6,7-dihydro-1H-indole-2-carboxylate (CAS 351073-97-7) is a high-purity analytical reference standard with the molecular formula C13H14ClNO3 and a molecular weight of 267.71 g/mol.
Ethyl 4-chloro-5-formyl-3-methyl-6,7-dihydro-1H-indole-2-carboxylate (C13H14ClNO3) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, 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. 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 Ethyl 4-chloro-5-formyl-3-methyl-6,7-dihydro-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.
