Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Rubidium dihydrogen phosphate (CAS 13774-16-8), a certified reference material (molecular formula O4PH2Rb, MW 182.45 g/mol) for analytical method development and quality control.
Owing to a phosphate ester group, Rubidium dihydrogen phosphate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
As a certified reference material (CRM), Rubidium dihydrogen 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.
