Chemical Structure
Description
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.
Trimethylsilyl 2-(dimethoxyphosphoryl)acetate (CAS 85169-29-5) is a high-purity analytical reference standard with the molecular formula C7H17O5PSi and a molecular weight of 240.27 g/mol.
Owing to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Trimethylsilyl 2-(dimethoxyphosphoryl)acetate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 240.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
