Sodium Nitrophenolate

Sodium Nitrophenolate for Agricultural Crop Formulations

Overview

Sodium Nitrophenolate is a multi-component plant growth regulator used in agricultural formulations. The technical material consists of a mixture of nitrophenolate components and is generally supplied as a crystalline powder. Commercial formulations are also available as aqueous liquids and wettable powders.

Technical-grade Sodium Nitrophenolate is commonly specified at 98%, while finished liquid formulations may be standardized at lower concentrations such as 1.4% or 1.8%. The technical material typically appears jujube-red to deep red and forms a reddish-brown solution when dissolved in water. Liquid formulations are generally tea-brown.

Typical applications include foliar plant growth regulator products and compatible fertilizer formulations. Product selection should distinguish between high-content technical material and ready-to-use or concentrated formulations.

Technical Specifications

Functional and Formulation Characteristics

Sodium Nitrophenolate differs from single-component plant growth regulators because its technical composition contains multiple nitrophenolate components. Consequently, quality evaluation should consider both overall specification and the analytical profile of the individual components.

Important formulation characteristics include:

• High-content technical material is supplied as a mixed crystalline powder.
• Suitable for preparation of lower-concentration agricultural formulations.
• Available in aqueous and wettable powder systems.
• Component composition can be evaluated by HPLC.
• Compatible fertilizer systems can be developed after formulation testing.
• pH and moisture are relevant routine quality parameters.

For liquid formulations, dissolution behavior, concentration, pH, water quality, and compatibility with other ingredients should be evaluated. In fertilizer blends, the behavior of the active components can also be influenced by the overall composition of the formulation.

Uniform distribution is important when preparing low-concentration products from technical-grade material. Manufacturing procedures should therefore be designed to maintain consistent active-component distribution.

Application Context

Sodium Nitrophenolate is incorporated into agricultural plant growth regulator formulations intended for foliar application and related crop-management programs. Finished-product concentration and application conditions should be determined according to the specific formulation and registered use.

It may also be incorporated into compatible fertilizer formulations. In these systems, formulators should assess solubility, pH, physical stability, and interactions with other fertilizer components before establishing the final composition.

Agricultural formulations containing Sodium Nitrophenolate may be developed for plant growth management, rooting-related applications, flowering and fruit-setting management, dormancy-related programs, and applications associated with crop stress or recovery following certain crop-treatment conditions.

Actual performance depends on crop species, growth stage, application concentration, timing, environmental conditions, and other formulation components. Product claims and application rates should therefore follow the regulatory and registration requirements applicable to the intended market and crop.

Composition and Standardization

Commercial Sodium Nitrophenolate technical material is commonly standardized at 98%, while finished formulations may contain substantially lower concentrations. HPLC can be used to evaluate the three individual components within the technical composition.

Routine quality-control parameters include:

• Active-component profile by HPLC.
• Technical material content.
• Moisture.
• pH for applicable formulations.
• Physical appearance.
• Batch consistency.

When comparing commercial products, buyers should confirm whether the declared concentration refers to technical material or a finished formulation. The analytical method and component-specific results should also be reviewed rather than relying solely on a single total-content value.

GB/T 37500-2019 may be referenced for applicable fertilizer testing. A batch-specific COA can provide corresponding analytical results. Technical powder should be stored in sealed packaging under dry conditions and protected from excessive heat and direct sunlight.
