Chemical Structure
Description
Rhenium heptasulfide, 99% 5GR (CAS 12038-67-4), molecular formula Re2S7 and molecular weight 596.87 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to sulfur-containing functionality, Rhenium heptasulfide, 99% 5GR is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 596.87 g/mol — guide the selection of appropriate sample preparation and analytical techniques.
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.
