Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
(R)-1-(1-Phenylethyl)-1H-pyrrole-2-carboxylic acid (CAS 173989-76-9), molecular formula C13H13NO2 and molecular weight 215.25 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (R)-1-(1-Phenylethyl)-1H-pyrrole-2-carboxylic acid (C13H13NO2) is characterized by a nitrogen-containing heterocyclic scaffold, 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).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
