Chemical Structure
Description
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.
(Lys(Me)??)-Histone H3 (1-21)-Gly-Gly-Lys(biotinyl) amide trifluoroacetate salt (CAS 2022956-73-4), molecular formula C117H212N43O32SC2HF3O2 and molecular weight 2879.33 g/mol, is a CATO reference standard with documented purity and traceability.
(Lys(Me)??)-Histone H3 (1-21)-Gly-Gly-Lys(biotinyl) amide trifluoroacetate salt (C117H212N43O32SC2HF3O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
As a certified reference material (CRM), (Lys(Me)??)-Histone H3 (1-21)-Gly-Gly-Lys(biotinyl) amide trifluoroacetate salt 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.
