Product Overview

Chromium(II) chloride (CrCl₂) at 99.9% purity (trace metal basis) is a highly reactive inorganic compound essential for advanced chemical synthesis and analytical procedures. This anhydrous form ensures minimal moisture interference, making it ideal for redox reactions, coordination chemistry, and as a precursor in organometallic synthesis. The ultra-high purity grade guarantees negligible trace metal contamination, critical for sensitive applications where impurities can compromise results. Its hygroscopic nature demands careful handling under inert conditions to maintain stability. The compound’s reducing properties and ability to form stable complexes with various ligands make it a versatile reagent in both research and industrial laboratories. Store under dry, oxygen-free conditions to prevent oxidation and degradation.

FAQs

1. What is the shelf life of Chromium(II) chloride if stored properly?

When stored under an inert atmosphere (e.g., nitrogen or argon) in a tightly sealed container, Chromium(II) chloride retains its purity for up to 2 years. Exposure to air or moisture significantly reduces stability.

2. Can this compound be used in aqueous solutions?

Chromium(II) chloride dissolves in water but rapidly oxidizes to Chromium(III) in the presence of oxygen. For aqueous applications, use deoxygenated solvents and work under inert conditions.

3. What are the key safety precautions for handling this product?

Wear gloves, goggles, and a lab coat in a fume hood. Avoid inhalation or skin contact, as it is corrosive and may cause irritation. Neutralize spills with a reducing agent before disposal.

4. Is this product compatible with standard glassware?

Yes, but ensure glassware is dry and free of oxidizing residues. Use PTFE-coated or inert containers for long-term storage to minimize reactions with trace impurities.

5. How does the trace metal basis purity differ from standard grades?

Trace metal basis indicates rigorous testing for metallic impurities (e.g., Fe, Ni, Cu), which are reduced to <0.01%. Standard grades may contain higher levels of these contaminants, affecting sensitive reactions.
