((R)-((S)-4,4-Dimethyl-1,3-dioxolan-2-yl)((trimethylsilyl)oxy)methyl)((R)-((R)-2,2-dimethyl-1,3-dioxolan-4-yl)((trimethylsilyl)oxy)methyl)(phenyl)phosphine oxide CAS 1955485-42-3 chemical structure

Description

The occurrence of ((R)-((S)-4,4-Dimethyl-1,3-dioxolan-2-yl)((trimethylsilyl)oxy)methyl)((R)-((R)-2,2-dimethyl-1,3-dioxolan-4-yl)((trimethylsilyl)oxy)methyl)(phenyl)phosphine oxide is closely related to a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies ((R)-((S)-4,4-Dimethyl-1,3-dioxolan-2-yl)((trimethylsilyl)oxy)methyl)((R)-((R)-2,2-dimethyl-1,3-dioxolan-4-yl)((trimethylsilyl)oxy)methyl)(phenyl)phosphine oxide (CAS 1955485-42-3), a certified reference material (molecular formula C24H43O7PSi2, MW 530.74 g/mol) for analytical method development and quality control.

((R)-((S)-4,4-Dimethyl-1,3-dioxolan-2-yl)((trimethylsilyl)oxy)methyl)((R)-((R)-2,2-dimethyl-1,3-dioxolan-4-yl)((trimethylsilyl)oxy)methyl)(phenyl)phosphine oxide (C24H43O7PSi2) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), ((R)-((S)-4,4-Dimethyl-1,3-dioxolan-2-yl)((trimethylsilyl)oxy)methyl)((R)-((R)-2,2-dimethyl-1,3-dioxolan-4-yl)((trimethylsilyl)oxy)methyl)(phenyl)phosphine oxide 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.
