4-(4-tert-Butylphenoxy)-2-{[(4-methylphenyl)methyl]sulfanyl}-5,6,7,8-tetrahydroquinazoline CAS 551921-45-0

Description

4-(4-tert-Butylphenoxy)-2-{[(4-methylphenyl)methyl]sulfanyl}-5,6,7,8-tetrahydroquinazoline (CAS 551921-45-0), molecular formula C26H30N2OS and molecular weight 418.59 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, 4-(4-tert-Butylphenoxy)-2-{[(4-methylphenyl)methyl]sulfanyl}-5,6,7,8-tetrahydroquinazoline is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 418.59 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.

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.

As a certified reference material (CRM), 4-(4-tert-Butylphenoxy)-2-{[(4-methylphenyl)methyl]sulfanyl}-5,6,7,8-tetrahydroquinazoline 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.
