1-(4-Phenoxyphenoxy)-2-propanol (CAS 95737-30-3), frequently referred to in the industry as "Pyriproxyfen Alcohol," is a sophisticated aromatic ether and secondary alcohol that serves as the definitive structural backbone for advanced insect growth regulators (IGRs). Features as a diphenyl ether moiety linked to a propan-2-ol side chain, a configuration assures specific molecular geometry required to mimic juvenile hormones in insects. In the agrochemical field, being an indispensable intermediate for the synthesis of Pyriproxyfen, a potent insecticide used globally for crop protection and public health (mosquito control). Beyond its agrochemical dominance, it is utilised as a high-purity building block in the development of speciality fragrances and performance polymers, where its ether linkages provide thermal stability and unique refractive properties. By maintaining stringent control over the "4-phenoxyphenoxy" isomeric purity, our exclusive grade ensures maximum conversion efficiency and bio-efficacy in the final active ingredients. We are a globally established specialty & Advanced Intermediates manufacturer and various other fine chemical intermediate suppliers worldwide through comprehensive regulatory documentation (CoA), traceability, and consistent global supply capabilities, ensuring reliable lead times and quality assurance across all grades.

Chemical Properties & Specifications
Primary precursor for Pyriproxyfen. Disrupting the hormonal balance in insects, preventing larvae from developing into adults
Manufacture formulations for the control of mosquitoes (Aedes aegypti), houseflies, and cockroaches, particularly in resistance management programs
Critical for the production of insecticides used in citrus, cotton, and greenhouse crops to target whiteflies and scale insects
Scaffold for synthesizing "woody" or "floral" aromatic ethers with high tenacity and stability in alkaline environments (like soaps)
Intermediate for aromatic-based UV absorbers due to its stable ether-linked phenolic structure
Explored in medicinal chemistry for the development of lipid-modulating agents and enzyme inhibitors
Store in a cool (15-25°C), dry place
Protect from strong light and oxidizing agents
Can transition between a solid and a viscous liquid depending on ambient temperature; gentle warming may be required for uniform sampling
Keep away from strong acids and acid chlorides, which can cause dehydration of the secondary alcohol or cleavage of the ether bonds.
The biological activity of the resulting insecticide (Pyriproxyfen) depends entirely on the linear, para-substitution of the diphenyl ether. If the substitution were at the ortho or meta positions, the molecule would not fit the insect's juvenile hormone receptor, rendering the final product ineffective.
No. It is a Specialty Intermediate. It requires further chemical reaction (typically with 2-chloropyridine) to become the active insecticide Pyriproxyfen.
Because this intermediate leads to IGRs (Insect Growth Regulators), it is part of a more sustainable pest management approach. IGRs are highly specific to insects and have very low toxicity to mammals, birds, and fish compared to older organophosphates.
