Chemical Structure
Description
The occurrence of Platinum nitrate solution is closely related to an inorganic composition in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Platinum nitrate solution (CAS 18496-40-7), a certified reference material (molecular formula PtNO3, MW 257.08 g/mol) for analytical method development and quality control.
Owing to an inorganic composition, Platinum nitrate solution is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 257.08 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
