What is Alpha Cypermethrin CAS 67375-30-8?

Alpha Cypermethrin is a technical-grade synthetic pyrethroid insecticide active ingredient. It is also known as alphamethrin and has the molecular formula C₂₂H₁₉Cl₂NO₃.

How does Alpha Cypermethrin differ from generic cypermethrin?

Alpha Cypermethrin is a stereochemically enriched form based on the more insecticidally active cis-isomers of cypermethrin. It is designed to provide higher activity at lower use rates than mixed-isomer technical cypermethrin.

Is Alpha Cypermethrin ready to apply directly?

No. This material is a technical-grade active ingredient for qualified formulators. It is used to manufacture end-use products such as emulsifiable concentrates, suspension concentrates and wettable powders.

What pests and crops is Alpha Cypermethrin used to control?

Formulated products are used against chewing and sucking pests such as lepidopteran larvae, aphids, thrips, whiteflies and beetles. Crop uses include cotton, corn, rice, citrus, vegetables, tobacco and tea, plus public-health control of flies and mosquitoes.

How should Alpha Cypermethrin technical material be stored and handled?

Keep it in tightly closed containers in a cool, dry, well-ventilated and secure area, away from heat, food, feed and strong oxidizing agents. Use suitable dust controls and personal protective equipment during weighing, transfer and formulation.

Product Description

Alpha Cypermethrin, CAS 67375-30-8, also known as alphamethrin, is a stereochemically enriched alpha-cyano pyrethroid insecticide; the EC/EINECS number is 257-842-9.

Synonyms: alphamethrin; cypermethrin alpha-isomer; alpha-cyano-3-phenoxybenzyl 3-(2,2-dichlorovinyl)-2,2-dimethylcyclopropanecarboxylate.

CAS: 67375-30-8.

Molecular formula: C₂₂H₁₉Cl₂NO₃.

Molecular weight: 416.30.

EC number: 257-842-9.

It is a white to off-white crystalline powder with a melting point of about 78–81 °C and a technical purity typically ≥95%.

It is insoluble in water and soluble in organic solvents such as xylene, acetone and methanol; the boiling point is about 300–310 °C (decomposes).

The vapor pressure is very low (about 1.5 × 10⁻⁷ mmHg at 25 °C); it is stable under normal storage and resistant to UV degradation.

It is used in crop protection against chewing and sucking pests on cotton, corn, rice, citrus, vegetables, tobacco and tea.

It is effective against lepidopteran larvae, coleopteran pests, aphids, thrips, whiteflies and beetles.

It is used in animal husbandry, grain storage and public-health pest control; it is a technical-grade active for qualified formulators, not for direct application.

Confirm purity, appearance, melting point, related isomers, water and residual solvents; it acts on insect sodium channels to cause paralysis and rapid knockdown.

Store in tightly closed containers in a cool, dry, well-ventilated, secure area, away from heat, food, feed and strong oxidizers; use dust controls and suitable PPE.
