Chemical Structure
Description
The occurrence of Diisobutyl hydrogen phosphate 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 Diisobutyl hydrogen phosphate (CAS 6303-30-6), a certified reference material (molecular formula C8H19O4P, MW 210.21 g/mol) for analytical method development and quality control.
Diisobutyl hydrogen phosphate (C8H19O4P) 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.
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), Diisobutyl hydrogen 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.
