Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies ethyl 2-methyl-2-(pyridin-4-yl)propanoate (CAS 205044-48-0), a certified reference material (molecular formula C11H15NO2, MW 193.24 g/mol) for analytical method development and quality control.
Structurally, ethyl 2-methyl-2-(pyridin-4-yl)propanoate (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 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).
As a certified reference material (CRM), ethyl 2-methyl-2-(pyridin-4-yl)propanoate 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.
