Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Tris(trimethylsilyl) Phosphite.
CATO supplies Tris(trimethylsilyl) Phosphite (CAS 1795-31-9), a certified reference material (molecular formula C9H27O3PSi3, MW 298.54 g/mol) for analytical method development and quality control.
The molecular framework of Tris(trimethylsilyl) Phosphite (C9H27O3PSi3) is characterized by a phosphonate group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
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.
