For agrochemical formulators, the precise specifications of raw materials are paramount to ensuring the efficacy, stability, and safety of their final products. Folcisteine, a vital plant growth regulator with CAS 5025-82-1, is no exception. Understanding its key characteristics, such as purity, appearance, and specific chemical properties, is essential before making a purchase. This guide outlines the critical specifications of high-purity Folcisteine 99.5%, emphasizing why sourcing from a quality-conscious manufacturer and supplier is crucial.

The most critical specification for Folcisteine is its assay, or purity level. For optimal performance in agricultural applications, a high purity of 99.5% or greater is desired. This ensures that the active compound is present in sufficient concentration to deliver the intended plant growth regulation effects, such as promoting seed germination and increasing fruit setting rate. When you buy Folcisteine, always verify the assay provided by the manufacturer.

Appearance is another important visual indicator of product quality. High-purity Folcisteine typically presents as a white or off-white powder. Any significant deviation in color or the presence of foreign matter could indicate contamination or degradation. This visual characteristic is often the first point of quality assessment for purchasing managers and R&D scientists.

The specific rotation, indicated as [α]20/D, is a crucial parameter for chiral compounds like Folcisteine, often falling within a range of -131° ±5° (C=2, H2O). This value helps confirm the stereochemical integrity of the molecule, which can directly influence its biological activity. Ensuring this parameter is within the specified range is a hallmark of a reputable supplier committed to product consistency.

Other important specifications include transmittance, which indicates the clarity of a solution and is usually required to be ≥99.0%. Limits for impurities such as chloride (CL ≤1.0%), iron (Fe ≤10ppm), and heavy metals (Pb ≤10ppm) are also vital for safety and regulatory compliance. Arsenic content must be strictly controlled, typically at ≤1ppm.

The melting point of Folcisteine typically ranges between 142°C and 149°C. This property is a classic indicator of purity and chemical identity. Furthermore, the loss on drying (≤0.5%) and TCL analysis (≥99.0%) contribute to the overall quality profile, ensuring the product is stable and free from excessive moisture or volatile components. These detailed technical parameters are what distinguish a professional manufacturer from others.

For businesses looking to purchase Folcisteine in bulk, understanding these specifications is key to making informed decisions. Working with a Chinese supplier that provides comprehensive technical data sheets (TDS) and Certificates of Analysis (CoA) for each batch assures you of the product's quality and consistency. This diligence is essential for formulators aiming to develop high-performance agrochemical products that meet market demands and regulatory requirements. If you are seeking a reliable source for high-quality Folcisteine, inquire about their detailed specifications and request a quotation today.
