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.
Potassium metaborate trihydrate (CAS 162379-51-3) is a high-purity analytical reference standard with the molecular formula BO2KH2O and a molecular weight of 99.92 g/mol.
Owing to an inorganic composition, Potassium metaborate trihydrate is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 99.92 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
