Chemical Structure

Ethyl 2-amino-9-methyl-5,6,7,8-tetrahydro-4h-5,8-epiminocyclohepta[b]thiophene-3-carboxylate CAS 1038330-43-6 chemical structure

Description

Ethyl 2-amino-9-methyl-5,6,7,8-tetrahydro-4h-5,8-epiminocyclohepta[b]thiophene-3-carboxylate (C13H18N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

Ethyl 2-amino-9-methyl-5,6,7,8-tetrahydro-4h-5,8-epiminocyclohepta[b]thiophene-3-carboxylate (CAS 1038330-43-6), molecular formula C13H18N2O2S and molecular weight 266.36 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), Ethyl 2-amino-9-methyl-5,6,7,8-tetrahydro-4h-5,8-epiminocyclohepta[b]thiophene-3-carboxylate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
