Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(4-Bromophenyl)-2-{[3-methyl-7-(4-methylphenyl)-4-oxo-3H,4H-thieno[3,2-d]pyrimidin-2-yl]sulfanyl}acetamide.
CATO supplies N-(4-Bromophenyl)-2-{[3-methyl-7-(4-methylphenyl)-4-oxo-3H,4H-thieno[3,2-d]pyrimidin-2-yl]sulfanyl}acetamide (CAS 1111318-01-4), a certified reference material (molecular formula C22H18BrN3O2S2, MW 500.43 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution, N-(4-Bromophenyl)-2-{[3-methyl-7-(4-methylphenyl)-4-oxo-3H,4H-thieno[3,2-d]pyrimidin-2-yl]sulfanyl}acetamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 500.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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), N-(4-Bromophenyl)-2-{[3-methyl-7-(4-methylphenyl)-4-oxo-3H,4H-thieno[3,2-d]pyrimidin-2-yl]sulfanyl}acetamide 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.
