For many technical buyers, registration teams and distributors, the first question about any active ingredient is simple: what is its CAS number and exact chemical name?
This article gives you a clear, business-focused overview of azoxystrobin CAS, azoxystrobin CAS number and azoxystrobin chemical name, and then connects that identity information to the typical needs of B2B buyers.
What Is the CAS Number of Azoxystrobin?
In technical and regulatory communication, the azoxystrobin CAS number is the primary identifier of this strobilurin fungicide.
Short definition (snippet-ready):
Azoxystrobin is a broad-spectrum strobilurin fungicide identified by the CAS number 131860-33-8, used globally to control a wide range of fungal diseases in major crops.
Why CAS Numbers Matter for Agrochemical Procurement
When your team evaluates a new supplier or prepares registration dossiers, the CAS number is the anchor that confirms you are discussing the same active ingredient across:
-
Registration files and ICAMA/other local submissions
-
COA, MSDS, TDS and analytical reports
-
Import/export customs documentation
-
Internal ERP and inventory codes
-
Multi-language labels and packaging artworks
Using the correct azoxystrobin CAS no (131860-33-8) avoids confusion with other strobilurin fungicides and reduces regulatory risk during registration, import and distribution.
Azoxystrobin Identity at a Glance
Technical buyers usually want a quick reference table to validate identity details provided by suppliers. Below is a structured summary.
Azoxystrobin Identity Data Table
| Item | Data |
|---|---|
| Active ingredient | Azoxystrobin |
| CAS number | 131860-33-8 |
| Azoxystrobin CAS no | 131860-33-8 (same as CAS number) |
| Chemical family | Strobilurin fungicide (methoxyacrylate class) |
| Azoxystrobin chemical name | Methyl (E)-2-{2-[6-(2-cyanophenoxy)pyrimidin-4-yloxy]methyl}-3-methoxyacrylate |
| IUPAC name (equivalent form) | Methyl (E)-2-{2-[6-(2-cyanophenoxy)pyrimidin-4-yloxy]methyl}-3-methoxyacrylate |
| Molecular formula | C₂₂H₁₇N₃O₅ |
| Mode of action group | QoI fungicide (complex III inhibitor, FRAC Group 11) |
This table gives your regulatory, QC and sourcing teams a single reference point when comparing offers from different azoxystrobin suppliers.

Azoxystrobin Chemical Name and How to Interpret It
Many buyers search for “azoxystrobin chemical name” to double-check that the substance offered by a supplier matches their internal specification.
IUPAC Name vs Common Name
-
Common name: Azoxystrobin
-
IUPAC / chemical name: Methyl (E)-2-{2-[6-(2-cyanophenoxy)pyrimidin-4-yloxy]methyl}-3-methoxyacrylate
The IUPAC name describes the exact structure and functional groups, while the common name “azoxystrobin” is what appears on labels, registrations and commercial documents. Both point to the same active ingredient defined by CAS 131860-33-8.
Functional Groups and Strobilurin Class
From the chemical name, you can infer several key elements that matter for formulators and R&D teams:
-
A methoxyacrylate group, typical for strobilurin fungicides
-
A pyrimidinyl ring connected via an ether linkage
-
A cyanophenoxy substituent, which contributes to biological activity and lipophilicity
These structural features help explain why azoxystrobin shows:
-
Strong activity against many Ascomycetes, Basidiomycetes and Deuteromycetes
-
Translaminar movement and partial systemic behavior
-
Compatibility with multiple formulation types (SC, WG, FS and others)
Key Chemical and Physical Properties for B2B Buyers
Beyond azoxystrobin CAS number, purchasing and technical teams usually review a short list of chemical properties before approving a supplier.
Core Physical Characteristics
Typical technical azoxystrobin (TC) is:
-
Appearance: Off-white to beige crystalline solid
-
Purity: Common commercial grades ≥ 95% (depending on specification and registration)
-
Molecular weight: Approx. 403.4 g/mol
-
Solubility: Low water solubility; good solubility in many organic solvents
-
Stability: Stable under normal dry storage conditions and neutral pH ranges
These characteristics influence how azoxystrobin behaves in suspension concentrates (SC), water-dispersible granules (WG) and seed treatment formulations (FS).
Storage Stability & Compatibility Considerations
Formulators and distributors typically pay attention to:
-
Stability under elevated temperature or cold storage (no significant degradation, no crystal growth)
-
Compatibility with common formulation adjuvants and dispersants
-
Low tendency to form hard sediment in SC/WG systems when properly formulated
Professional suppliers will normally provide stability data, accelerated storage results and compatibility notes as part of the technical dossier to support your quality review.
Where Azoxystrobin Is Commonly Used (Non-Instructional Overview)
This section is not a use guide. It simply positions azoxystrobin within global crop protection markets.
Major Crop Segments
Azoxystrobin is widely used by formulators and brand owners in products registered for:
-
Cereals (wheat, barley, corn, etc.)
-
Rice
-
Grapes
-
Fruits and vegetables
-
Turf and ornamentals
Due to its broad-spectrum activity, it is often included in solo products and mixtures targeting multiple key diseases.
Typical Disease Targets
In many markets, azoxystrobin-based products are registered to help control diseases such as:
-
Rusts
-
Powdery mildew
-
Leaf spots and blights
-
Anthracnose
-
Certain seed-borne and soil-borne pathogens (via seed treatment or soil-related registrations)
Exact use patterns and label claims depend on local registrations and regulations in each country.
Always follow the approved product label and local regulations in your market. This article is for technical information only, not for field-use instructions.
Safety and Regulatory Perspective
When your team evaluates azoxystrobin, you not only check azoxystrobin CAS and purity, but also its toxicological and environmental profile as defined in official assessments.
High-Level Toxicological View
Publicly available data classifies azoxystrobin as having:
-
Low acute toxicity for mammals when used as directed
-
Specific hazard classifications regarding aquatic organisms, which is typical for many fungicides
-
Defined ADI (Acceptable Daily Intake) and ARfD (Acute Reference Dose) values set by regulatory authorities
Your registration and stewardship teams will typically review full toxicology, eco-toxicity and residue evaluation documents, supplied along with MSDS and TDS.
Compliance, Labeling and Documentation
For importers and brand owners, a compliant azoxystrobin offer should be backed by:
-
COA for every batch, linked to azoxystrobin CAS number 131860-33-8
-
MSDS in required languages
-
TDS / specification sheet
-
Support for local registration dossiers (on request)
Professional suppliers will also support multi-language labels and transport documentation to match local law.
