Streamlining Yttrium Oxide Compliance and Safety Data Management

A consolidated review of major chemical-safety databases has brought together 17 authoritative records on yttrium oxide (Y2O3) and related CAS variants, including 1314-36-9, 11130-29-3 and 12036-00-9. The update is intended to give chemical managers a more precise route for retrieving safety, exposure and classification data for compliance reviews.

Core data resources consolidated

The review draws on regulatory, ecological and technical sources to assemble a complete chain of information, from exposure assessment and toxicological properties to Globally Harmonized System classification. The records cover the standard identifier CAS No. 1314-36-9 as well as variants associated with CAS Nos. 11130-29-3 and 12036-00-9.

The collection is intended to support compliance reviews by giving safety managers a structured set of references for substance identification and hazard evaluation. The sources include official regulatory databases, environmental exposure tools and technical reference platforms.

Compliance management recommendations

When handling yttrium oxide materials, companies should prioritize entries with the closest match to the substance under review for risk assessment. Because databases differ in how they classify variants, safety managers should cross-check exposure limits and protective recommendations across sources when preparing or updating Safety Data Sheets.

That cross-verification is intended to help align workplace safety documentation with the requirements of the regions where products are sold or used. It also helps clarify whether a record applies directly to the substance or to a related form.

Distinguishing CAS variants and data quality

CAS No. 1314-36-9 is the standard identifier for yttrium oxide. CAS Nos. 11130-29-3 and 12036-00-9 generally refer to forms with different physical characteristics or hydrate compositions, so property descriptions should be compared and supplier technical specifications verified when necessary.

A high match rating indicates that source data closely correspond to the chemical characteristics of the target substance and can serve as a direct compliance reference. Medium or low ratings suggest that the data may be based on analogues or broad categories and should be supplemented with internal toxicological test results.
