| Property | Value |
| Molecular Formula | C₁₂H₂₂O |
| Molecular Weight | 182.30 g/mol |
| Chemical Class | Cyclopropyl alcohol derivative |
| Functional Groups | Alcohol, alkene, cyclopropane ring |
| Physical State | Not consistently disclosed publicly |
| Purity(GC) | >98% |
Fragrance and Olfactory Characteristics
Industry discussions and regulatory disclosures indicate that the material is associated with fine fragrance and aroma chemical applications under the name “Rosyfolia.” Public fragrance-community discussions describe the odor profile as having:
- Geraniol-like floral nuances
- Fruity tonalities
- Airy and diffusive characteristics
These descriptions originate from industry-user discussions rather than formal specification sheets and should therefore be interpreted cautiously.
Industrial Uses and Applications
- Fragrance Industry
The principal documented application of CAS 1655500-83-6 is in fragrance compositions and perfumery materials.
Regulatory and safety documentation show its inclusion in:
- Air freshener systems
- Home fragrance products
- Consumer scent formulations
The compound appears in fragrance formulations at low concentrations, consistent with the use of high-impact aroma ingredients. Safety data sheets from commercial fragrance products identify the substance as a minor constituent in blended fragrance systems.
- Specialty Chemical Manufacturing
Chemical manufacturing databases classify the substance within:
- Specialty chemical production
- Chemical preparation manufacturing
Its structure suggests suitability as an intermediate or performance additive for aroma and flavor chemistry, although publicly verified industrial synthesis routes are not widely disclosed.
- Consumer Products
Documented downstream applications include:
- Automated air freshening systems
- Scented household products
- Ambient fragrance delivery products
Regulatory and Commercial Status
Australian industrial chemical assessment documentation records that the substance was notified internationally in:
- China
- European Union
- Switzerland
- United States
with notification dates around 2015.
The same dossier identifies:
- Marketing name: Rosyfolia
- Internal designation: GR-50-1408
The chemical has also appeared in supplier catalogs from specialty chemical vendors.
Safety and Hazard Information
Available Safety Data Sheet (SDS) disclosures classify the material with several hazard categories when present in mixtures, including:
- Skin irritation
- Eye irritation
- Skin sensitization
- Aquatic chronic toxicity
A toxicological assessment referenced in an industrial chemical report noted evidence of skin sensitization in test conditions.
General handling recommendations from associated SDS documentation include:
- Use of protective gloves and eye protection
- Adequate ventilation
- Avoidance of prolonged skin exposure
Because publicly available toxicological data remain incomplete, industrial users typically rely on supplier SDS documentation and regional chemical regulations for operational handling guidance.
Commercial and Technical Significance
CAS 1655500-83-6 represents a modern specialty fragrance ingredient with likely emphasis on:
- Diffusive floral effects
- Fruity-floral modulation
- Low-dose performance in fragrance accords
Its cyclopropane-containing structure distinguishes it from more conventional terpene alcohols and may contribute to specific odor diffusion or stability characteristics, although detailed proprietary performance data are not publicly available.
The material appears to occupy a niche role in premium fragrance formulation and functional scent systems rather than large-volume commodity chemical production.
Conclusion
This compound (CAS No. 1655500-83-6) is a specialty fragrance-related chemical primarily associated with the trade name Rosyfolia. Available public information supports its use in fragrance and air-care formulations, where it contributes floral and fruity odor characteristics. Regulatory records and SDS documents confirm its commercial use in low concentrations within consumer fragrance products. However, publicly available physicochemical and toxicological datasets remain limited, and much of the detailed performance information appears proprietary to fragrance manufacturers.
