Chemical Structure
Description
Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 2-Mercapto-3-(7-methyloctyl)quinazolin-4(3H)-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 304.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
2-Mercapto-3-(7-methyloctyl)quinazolin-4(3H)-one (CAS 731776-64-0), molecular formula C17H24N2OS and molecular weight 304.45 g/mol, is a CATO reference standard with documented purity and traceability.
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.
