The occurrence of Ammonium Fluorosilicate is closely related to fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ammonium Fluorosilicate (CAS 16919-19-0) is a high-purity analytical reference standard with the molecular formula F6SiH4N and a molecular weight of 160.11 g/mol.
Ammonium Fluorosilicate (F6SiH4N) contains fluorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), Ammonium Fluorosilicate 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.
