Chemical Structure
Description
As a certified reference material (CRM), Tris(2-methoxyethyl) phosphate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
Tris(2-methoxyethyl) phosphate (CAS 6163-73-1) is a high-purity analytical reference standard with the molecular formula C9H21O7P and a molecular weight of 272.23 g/mol.
Tris(2-methoxyethyl) phosphate (C9H21O7P) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.
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.
