Chemical Structure

Iron(II) sulfide CAS 1317-37-9 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 Iron(II) sulfide.

Iron(II) sulfide (CAS 1317-37-9), molecular formula FeS and molecular weight 87.91 g/mol, is a CATO reference standard with documented purity and traceability.

Iron(II) sulfide (FeS) 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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
