Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3-Methylthiophen-2-yl)(pyridin-2-yl)methanone.
(3-Methylthiophen-2-yl)(pyridin-2-yl)methanone (CAS 1373519-81-3) is a high-purity analytical reference standard with the molecular formula C11H9NOS and a molecular weight of 203.26 g/mol.
The molecular framework of (3-Methylthiophen-2-yl)(pyridin-2-yl)methanone (C11H9NOS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, 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), (3-Methylthiophen-2-yl)(pyridin-2-yl)methanone 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.
