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.
CATO supplies 556-81-0 Hexamethonium hydroxide solution N,N,N,N inverted exclamation marka,N inverted exclamation marka,N inverted exclamation marka-Hexamethylhexamethylenediammonium dihydroxide (CAS 556-81-0), a certified reference material (molecular formula C12H30N2HO, MW 219.39 g/mol) for analytical method development and quality control.
556-81-0 Hexamethonium hydroxide solution N,N,N,N inverted exclamation marka,N inverted exclamation marka,N inverted exclamation marka-Hexamethylhexamethylenediammonium dihydroxide (C12H30N2HO) contains an amide group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.
As a certified reference material (CRM), 556-81-0 Hexamethonium hydroxide solution N,N,N,N inverted exclamation marka,N inverted exclamation marka,N inverted exclamation marka-Hexamethylhexamethylenediammonium dihydroxide 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.
