Chemical Structure
Description
As a certified reference material (CRM), Phosphoric acid chloromethyl ester bis-(2-trimethylsilanyl-ethyl) ester 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.
CATO supplies Phosphoric acid chloromethyl ester bis-(2-trimethylsilanyl-ethyl) ester (CAS 1234692-55-7), a certified reference material (molecular formula C11H28ClO4PSi2, MW 346.94 g/mol) for analytical method development and quality control.
The molecular framework of Phosphoric acid chloromethyl ester bis-(2-trimethylsilanyl-ethyl) ester (C11H28ClO4PSi2) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
