Chemical Structure

Tris(trimethylsilyl) Phosphate CAS 10497-05-9 chemical structure

Description

Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Tris(trimethylsilyl) Phosphate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.54 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

Tris(trimethylsilyl) Phosphate (CAS 10497-05-9), molecular formula C9H27O4PSi3 and molecular weight 314.54 g/mol, is a CATO reference standard with documented purity and traceability.

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.

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.
