Chemical Structure
Description
Ethyl 2-Amino-1-methyl-1H-pyrrole-3-carboxylate (CAS 108290-89-7), molecular formula C8H12N2O2 and molecular weight 168.19 g/mol, is a CATO reference standard with documented purity and traceability.
Ethyl 2-Amino-1-methyl-1H-pyrrole-3-carboxylate (C8H12N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 2-Amino-1-methyl-1H-pyrrole-3-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.
