Chemical Structure

Potassium sulfide anhydrous CAS 1312-73-8 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 Potassium sulfide anhydrous.

Potassium sulfide anhydrous (CAS 1312-73-8), molecular formula K2S and molecular weight 110.26 g/mol, is a CATO reference standard with documented purity and traceability.

Potassium sulfide anhydrous (K2S) contains sulfur-containing functionality. Its physicochemical properties are representative of its class; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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), Potassium sulfide anhydrous 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.
