Product Description
Seller Information

Description
5,7-Dimethoxy-2,2-dimethylchromene (also categorized as a synthetic precocenoid; CAS 21421-66-9) functions primarily as an insect growth regulator, an anti-juvenile hormone probe, and a specialized agrochemical testing agent.

It is a structural isomer and synthetic analog of the naturally occurring plant defense compounds known as precocenes (such as precocene I and precocene II), which are natively secreted by species like Ageratum houstonianum to ward off predatory pests.

Core Functions and Research Applications

Anti-Juvenile Hormone (AJH) Activity: Like its natural counterparts, this chromene derivative acts as an anti-juvenile hormone agent. It interferes with the insect endocrine system, precisely targetting the corpora allata gland responsible for secreting juvenile hormones. This disruption forces immature nymphs or larvae to undergo premature (precocious) metamorphosis into sterile, malformed, or non-viable adults.

Targeted Insect Control Screening: In entomological and agricultural research, it is applied as a bioactive screening molecule to evaluate pest management efficacy. For example, laboratory assays demonstrate that it functions effectively in hemipteran models, inducing severe systemic effects like a loss of pigmentation in the hatching larvae of shield bugs (Eurygaster integriceps).

Antifungal and Antimicrobial Profiling: Beyond its properties as a biopesticide, the 2,2-dimethylchromene core structure is extensively investigated in chemical biology for its broad-spectrum antifungal mechanisms. It is used as a screening template to design synthetic derivatives capable of suppressing mycotoxins and blocking crop-destroying fungal pathogens without requiring heavily toxic, traditional chemical treatments.

Structure-Activity Relationship (SAR) Probe: Because it varies the placement of its methoxy groups (at positions 5 and 7) compared to natural precocene II (which features methoxy groups at positions 6 and 7), synthetic and medicinal chemists utilize this compound to map out the exact molecular boundaries of insecticidal potency. This makes it a crucial tool for optimizing the success rate of green chemistry drug pipelines.
