L-Proline 99% Crystalline Powder
High-Purity Plant Osmoprotectant & Cold/Drought Stress Biostimulant
Nova-Agri Biotech supplies L-Proline 99% Crystalline Powder (CAS 147-85-3, C5H9NO2) — a high-purity amino acid plant biostimulant and osmoprotectant used in foliar sprays, fertigation and biostimulant formulations to protect crops against drought, frost and salinity stress. L-Proline is a naturally occurring amino acid that plants accumulate under stress; supplementing it externally helps crops maintain cell turgor, stabilize membranes and keep photosynthesis running during cold snaps, heatwaves and dry periods. Key specifications: assay ≥99%, white crystal or crystalline powder, 100% water-soluble at 20 °C, pH 5.9–6.9, moisture ≤0.3%, heavy metals Pb/As/Cd/Hg ≤1 ppm, verified by a batch COA for every shipment. Packed in 25 kg bags (custom OEM packaging available), MOQ 500 kg. Standard lead time: approximately 10 working days to Shanghai port after payment confirmation, with a batch COA for every shipment. As a leading L-Proline manufacturer in China, we offer direct bulk supply and full technical documentation for agrochemical distributors and formulators worldwide. For formulators: add 2.0–10.0 kg per 1,000 L (0.2%–1.0% w/v) in liquid biostimulant blends, 5.0–20.0 kg per metric ton (0.5%–2.0% w/w) in dry blends, or 10.0–30.0 kg per 1,000 L (1.0%–3.0% w/v) in high-concentration concentrates diluted 1:500–1:1,000. For field use: apply 200–500 g/ha as a foliar spray (working solution 0.02–0.05% w/v, approx. 200–500 ppm; dilute approx. 1:2,000–1:5,000 in water) 24–48 hours before expected frost or heat events; 1.0–2.0 kg/ha via drip irrigation during prolonged drought or high-EC salinity stress; or 0.5–1.5 g per kg of seed for seed treatment.
