Chemical Structure

2-(Pyridin-4-yl)-3-(m-tolyl)quinazoline-4(3H)-thione CAS 61351-69-7 chemical structure

Description

As a certified reference material (CRM), 2-(Pyridin-4-yl)-3-(m-tolyl)quinazoline-4(3H)-thione 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.

2-(Pyridin-4-yl)-3-(m-tolyl)quinazoline-4(3H)-thione (CAS 61351-69-7) is a high-purity analytical reference standard with the molecular formula C20H15N3S and a molecular weight of 329.42 g/mol.

The molecular framework of 2-(Pyridin-4-yl)-3-(m-tolyl)quinazoline-4(3H)-thione (C20H15N3S) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. 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 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.
