Chemical Structure

Ethyl 3,4,5-trimethyl-1H-pyrrole-2-carboxylate CAS 2199-46-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 181.23 g/mol gives Ethyl 3,4,5-trimethyl-1H-pyrrole-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ethyl 3,4,5-trimethyl-1H-pyrrole-2-carboxylate (CAS 2199-46-4), a certified reference material (molecular formula C10H15NO2, MW 181.23 g/mol) for analytical method development and quality control.

The molecular framework of Ethyl 3,4,5-trimethyl-1H-pyrrole-2-carboxylate (C10H15NO2) is characterized by an amino-acid-derived structure, an amide 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 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), Ethyl 3,4,5-trimethyl-1H-pyrrole-2-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.
