Chemical Structure
Description
As a certified reference material (CRM), 2-Ethyl-6-methylisonicotinic acid ethyl ester 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.
2-Ethyl-6-methylisonicotinic acid ethyl ester (CAS 1122091-59-1) is a high-purity analytical reference standard with the molecular formula C11H15NO2 and a molecular weight of 193.24 g/mol.
Structurally, 2-Ethyl-6-methylisonicotinic acid ethyl ester (C11H15NO2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 193.24 g/mol, it falls into the medium-molecular-weight range. 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.
