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 1-{4-methoxy-3-[(pyrimidin-2-ylsulfanyl)methyl]phenyl}ethan-1-one.
1-{4-methoxy-3-[(pyrimidin-2-ylsulfanyl)methyl]phenyl}ethan-1-one (CAS 733044-95-6), molecular formula C14H14N2O2S and molecular weight 274.34 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, 1-{4-methoxy-3-[(pyrimidin-2-ylsulfanyl)methyl]phenyl}ethan-1-one (C14H14N2O2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 274.34 g/mol, it falls into the medium-molecular-weight range. 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), 1-{4-methoxy-3-[(pyrimidin-2-ylsulfanyl)methyl]phenyl}ethan-1-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.
