Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 155.15 g/mol gives 2-Hydroxyethyl 1H-pyrrole-2-carboxylate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
2-Hydroxyethyl 1H-pyrrole-2-carboxylate (CAS 668987-22-2), molecular formula C7H9NO3 and molecular weight 155.15 g/mol, is a CATO reference standard with documented purity and traceability.
2-Hydroxyethyl 1H-pyrrole-2-carboxylate (C7H9NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 2-Hydroxyethyl 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.
