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 Imino(methyl)(4-methylphenyl)-lambda6-sulfanone.
Imino(methyl)(4-methylphenyl)-lambda6-sulfanone (CAS 22132-97-4), molecular formula C8H11NOS and molecular weight 169.24 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, Imino(methyl)(4-methylphenyl)-lambda6-sulfanone is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 169.24 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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), Imino(methyl)(4-methylphenyl)-lambda6-sulfanone 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.
