Chemical Structure
Description
The occurrence of 5-Ethyl-2-methylisonicotinic acid is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-Ethyl-2-methylisonicotinic acid (CAS 855270-32-5) is a high-purity analytical reference standard with the molecular formula C9H11NO2 and a molecular weight of 165.19 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 5-Ethyl-2-methylisonicotinic acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 165.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
