Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (1Z,3Z)-4-(dimethylamino)-1-[(dimethylamino)methylidene]-1,3-bis(phenylsulfanyl)but-3-en-2-one 338777-86-9 6B-067.
(1Z,3Z)-4-(dimethylamino)-1-[(dimethylamino)methylidene]-1,3-bis(phenylsulfanyl)but-3-en-2-one 338777-86-9 6B-067 (CAS 338777-86-9), molecular formula C21H24N2OS2 and molecular weight 384.56 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (1Z,3Z)-4-(dimethylamino)-1-[(dimethylamino)methylidene]-1,3-bis(phenylsulfanyl)but-3-en-2-one 338777-86-9 6B-067 (C21H24N2OS2) is characterized by a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), (1Z,3Z)-4-(dimethylamino)-1-[(dimethylamino)methylidene]-1,3-bis(phenylsulfanyl)but-3-en-2-one 338777-86-9 6B-067 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.
