For industries relying on high-purity chemical compounds, understanding the detailed specifications of ingredients like L-Proline is crucial. As a key component in both pharmaceutical infusions and advanced infant nutrition, the quality and consistency of L-Proline are non-negotiable. NINGBO INNO PHARMCHEM CO.,LTD. ensures that its L-Proline meets exacting standards, providing users with confidence in its application. The product is characterized by its white crystalline powder form, often with a slight, characteristic odor and a mildly sweet taste, making it amenable to formulation.

The assay of L-Proline, typically ranging from 99.0% to 101.0% on a dry basis, signifies its high purity. This level of precision is vital for pharmaceutical applications where even minor impurities can affect efficacy or safety. Further critical specifications include the state of solution, measured by transmittance (not less than 98.0%), and pH (5.9-6.9). These parameters are indicative of the product's solubility and chemical stability. For those looking to buy L-Proline, examining these specifications is a key step in ensuring product suitability. NINGBO INNO PHARMCHEM CO.,LTD. provides this detailed information, acting as a transparent and reliable supplier.

Control of impurities is another cornerstone of high-quality L-Proline. Limits for ammonium (not more than 0.020%), chloride (not more than 0.020%), and sulfate (not more than 0.020%) are strictly monitored. Similarly, stringent limits are placed on heavy metals like lead (not more than 10 ppm, with an FCC grade option for 5 mg/kg) and arsenic (not more than 1 ppm). Loss on drying is kept to a minimum (not more than 0.25%), and residue on ignition (not more than 0.10%) further confirms the absence of inorganic contaminants. These measures are essential when sourcing USP grade L-Proline for critical applications. The expertise of NINGBO INNO PHARMCHEM CO.,LTD. as a manufacturer guarantees adherence to these demanding standards, offering a competitive price for unparalleled quality.

Specific rotation, an indicator of chiral purity, is also meticulously controlled, with values for [α]20D between -84.5° and -86.0°, and for [α]25D between -84.3° and -86.3°. These precise measurements underscore the product's consistency and stereochemical integrity. For applications requiring endotoxin control, an endotoxin-certified grade is available upon request, further demonstrating the company's commitment to meeting specialized market needs. By understanding these detailed L-Proline specifications, clients can confidently select NINGBO INNO PHARMCHEM CO.,LTD. as their preferred supplier for pharmaceutical and nutritional ingredients.
