Chemical Structure

3-Butyl-2-mercapto-3H-quinazolin-4-one CAS 13906-07-5 chemical structure

Description

As a certified reference material (CRM), 3-Butyl-2-mercapto-3H-quinazolin-4-one 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.

CATO supplies 3-Butyl-2-mercapto-3H-quinazolin-4-one (CAS 13906-07-5), a certified reference material (molecular formula C12H14N2OS, MW 234.32 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 3-Butyl-2-mercapto-3H-quinazolin-4-one is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 234.32 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).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
