Chemical Structure

Pirfenidone CAS 53179-13-8 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 185.22 g/mol gives Pirfenidone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Pirfenidone (CAS 53179-13-8) is a high-purity analytical reference standard with the molecular formula C12H11NO and a molecular weight of 185.22 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, Pirfenidone is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 185.22 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), Pirfenidone 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.
