Core physical data (mp, density, solubility, pH, storage guidance) are listed in compiled property sheets for CAS 13494‑98‑9.

4. Chemical properties

• Oxidizing nature: Nitrate salt; may intensify fire (oxidizer)

• Reactivity: Reacts with organics/reducing agents; moisture sensitive

• Stability: Decomposes upon heating; store sealed and cool

General oxidizer behavior and stability guidance follow standard nitrate salt handling and supplier safety notes for the hexahydrate.

5. Applications

• Advanced ceramics and glass: precursor for yttrium-containing materials

• Optics and electronics: rare earth reagent for coatings and thin films

• Laboratory reagent: high‑purity indium/yttrium chemistry and REO work

Use cases (optics, ceramics, electronics, reagent) are highlighted by specialty rare‑earth suppliers for high‑purity grades.

6. Packaging and logistics

• Forms: Crystals and lumps; sometimes granular

• Storage: Cool, dry, sealed; protect from moisture

• Transport classification: Typically oxidizing substance (ADR/IMDG/IATA)

Packaging forms and storage advice reflect supplier listings and oxidizer categorization norms for nitrate hydrates.

7. Regulatory and safety

• GHS/CLP: Oxidizing; harmful if swallowed; irritant

• Label notes (typical): H272 (oxidizer) and H302 (harmful if swallowed) may apply based on SDS

• Documentation: COA/COO and MSDS available from suppliers

Safety and documentation expectations are consistent with supplier pages and compiled SDS references for the hexahydrate.

8. Quality and certification

• Production: ISO 9001 compliant (common for rare earth producers)

• Grades: Trace metals basis and ultra‑high purity (≥99.99%) for research/industrial

Grade availability and quality documentation are indicated by multiple vendors of CAS 13494‑98‑9.
