Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 11,11 inverted exclamation marka-Dithiobis[1-(2-bromo-2-methylpropionyloxy)undecane] 402828-41-5 Bis[2-(2-bromoisobutyryloxy)undecyl] disulfide DTBU.

CATO supplies 11,11 inverted exclamation marka-Dithiobis[1-(2-bromo-2-methylpropionyloxy)undecane] 402828-41-5 Bis[2-(2-bromoisobutyryloxy)undecyl] disulfide DTBU (CAS 402828-41-5), a certified reference material (molecular formula C30H56Br2O4S2, MW 704.70 g/mol) for analytical method development and quality control.

11,11 inverted exclamation marka-Dithiobis[1-(2-bromo-2-methylpropionyloxy)undecane] 402828-41-5 Bis[2-(2-bromoisobutyryloxy)undecyl] disulfide DTBU (C30H56Br2O4S2) contains a sulfone group, a carboxylic acid 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. 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), 11,11 inverted exclamation marka-Dithiobis[1-(2-bromo-2-methylpropionyloxy)undecane] 402828-41-5 Bis[2-(2-bromoisobutyryloxy)undecyl] disulfide DTBU 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.
