Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 213.30 g/mol gives Ethyl 2-amino-5-isopropylthiophene-3-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Ethyl 2-amino-5-isopropylthiophene-3-carboxylate (CAS 65416-85-5), molecular formula C10H15NO2S and molecular weight 213.30 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Ethyl 2-amino-5-isopropylthiophene-3-carboxylate (C10H15NO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Ethyl 2-amino-5-isopropylthiophene-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.
