Chemical Structure

Orthosilicic acid CAS 10193-36-9 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Orthosilicic acid.

Orthosilicic acid (CAS 10193-36-9), molecular formula H4O4Si and molecular weight 96.11 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Orthosilicic acid (H4O4Si) is characterized by an inorganic composition. 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.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

As a certified reference material (CRM), Orthosilicic acid 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.
