Chemical Structure
Description
The molecular framework of Strontium pyrophosphate (O7P2Sr) is characterized by a phosphate ester group. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development.
Strontium pyrophosphate (CAS 13812-81-2), molecular formula O7P2Sr and molecular weight 261.56 g/mol, is a CATO reference standard with documented purity and traceability.
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), Strontium pyrophosphate 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.
