Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N-(4-bromo-2-methylphenyl)-2-((3-cyano-4-(trifluoromethyl)-6,7,8,9-tetrahydro-5H-cyclohepta[b]pyridin-2-yl)thio)acetamide.
N-(4-bromo-2-methylphenyl)-2-((3-cyano-4-(trifluoromethyl)-6,7,8,9-tetrahydro-5H-cyclohepta[b]pyridin-2-yl)thio)acetamide (CAS 626227-38-1) is a high-purity analytical reference standard with the molecular formula C21H19BrF3N3OS and a molecular weight of 498.36 g/mol.
Structurally, N-(4-bromo-2-methylphenyl)-2-((3-cyano-4-(trifluoromethyl)-6,7,8,9-tetrahydro-5H-cyclohepta[b]pyridin-2-yl)thio)acetamide (C21H19BrF3N3OS) contains a steroid core, an amide group, sulfur-containing functionality, a hydroxyl group, an ether linkage, fluorine/bromine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.0, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 498.36 g/mol, it falls into the moderately-high-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-bromo-2-methylphenyl)-2-((3-cyano-4-(trifluoromethyl)-6,7,8,9-tetrahydro-5H-cyclohepta[b]pyridin-2-yl)thio)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.
