4-Hydroxy-7,8,9,10-tetrahydropyrimido[4',5':4,5]thieno[2,3-b]quinolin-2(1H)-one CAS 712344-92-8

Description

4-Hydroxy-7,8,9,10-tetrahydropyrimido[4',5':4,5]thieno[2,3-b]quinolin-2(1H)-one (CAS 712344-92-8) is a high-purity analytical reference standard with the molecular formula C13H11N3O2S and a molecular weight of 273.31 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 4-Hydroxy-7,8,9,10-tetrahydropyrimido[4',5':4,5]thieno[2,3-b]quinolin-2(1H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 273.31 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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-Hydroxy-7,8,9,10-tetrahydropyrimido[4',5':4,5]thieno[2,3-b]quinolin-2(1H)-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.
