Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 199.21 g/mol gives 5-Phenylnicotinic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
5-Phenylnicotinic acid (CAS 10177-12-5) is a high-purity analytical reference standard with the molecular formula C12H9NO2 and a molecular weight of 199.21 g/mol.
Owing to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage, 5-Phenylnicotinic acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 199.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-Phenylnicotinic acid 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.
