Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (4-BROMOPHENYL)(ISOCYANO)METHYL 4-METHYLPHENYL SULFONE (4-BROMOPHENYL)(ISOCYANO)METHYL 4-METHYLPHENYL SULPHONE 1-BROMO-4-[ISOCYANO[(4-METHYLPHENYL)SULFONYL]METHYL]BENZENE 4-BROMO-1-[ISOCYANO-(TOLUENE-4-SULFONYL)-METHYL]-BENZENE 655254-61-8 BC003619 [1-(4-BROMOPHENYL)-1-TOSYL]METHYL ISOCYANIDE.

(4-BROMOPHENYL)(ISOCYANO)METHYL 4-METHYLPHENYL SULFONE (4-BROMOPHENYL)(ISOCYANO)METHYL 4-METHYLPHENYL SULPHONE 1-BROMO-4-[ISOCYANO[(4-METHYLPHENYL)SULFONYL]METHYL]BENZENE 4-BROMO-1-[ISOCYANO-(TOLUENE-4-SULFONYL)-METHYL]-BENZENE 655254-61-8 BC003619 [1-(4-BROMOPHENYL)-1-TOSYL]METHYL ISOCYANIDE (CAS 655254-61-8), molecular formula C15H12BrNO2S and molecular weight 350.23 g/mol, is a CATO reference standard with documented purity and traceability.

(4-BROMOPHENYL)(ISOCYANO)METHYL 4-METHYLPHENYL SULFONE (4-BROMOPHENYL)(ISOCYANO)METHYL 4-METHYLPHENYL SULPHONE 1-BROMO-4-[ISOCYANO[(4-METHYLPHENYL)SULFONYL]METHYL]BENZENE 4-BROMO-1-[ISOCYANO-(TOLUENE-4-SULFONYL)-METHYL]-BENZENE 655254-61-8 BC003619 [1-(4-BROMOPHENYL)-1-TOSYL]METHYL ISOCYANIDE (C15H12BrNO2S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, bromine substitution. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
