Chemical Structure
Description
The occurrence of 5-(Ethoxymethyl)-1,3-dimethyl-1H-pyrazole is closely related to an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5-(Ethoxymethyl)-1,3-dimethyl-1H-pyrazole (CAS 91026-98-1) is a high-purity analytical reference standard with the molecular formula C8H14N2O and a molecular weight of 154.21 g/mol.
The molecular framework of 5-(Ethoxymethyl)-1,3-dimethyl-1H-pyrazole (C8H14N2O) is characterized by an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
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), 5-(Ethoxymethyl)-1,3-dimethyl-1H-pyrazole 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.
