Import 3-Indolebutyric Acid (Iba) — Buy in Bulk from Supplier in China

3-Indolebutyric acid (IBA, CAS 133-32-4) is a synthetic auxin plant growth regulator supplied by Xinyi Industrial Co., Ltd from Shanghai, China. This listing presents IBA as a powder with a stated assay of 98%, a concentration that targets commercial propagation and tissue culture applications. The chemical structure C12H13NO2 places it within the indole-3-acetic acid analog class, where the butyric side chain slows metabolic breakdown to deliver prolonged rooting stimulus compared to native auxins. Buyers should confirm the exact grade, as pharmaceutical, reagent, and agricultural grades carry different impurity profiles and regulatory statuses.

The 98% assay figure refers to the active ingredient content, with the remaining 2% comprising synthesis residues, moisture, and inorganic salts typical of technical-grade auxins. Standard manufacturing routes include indole ring construction followed by Friedel-Crafts acylation and subsequent reduction, or indole-3-acetaldehyde oxidation variants. The powder form specified here requires protection from light and moisture, as IBA degrades through photo-oxidation and hydrolysis, particularly in alkaline conditions. Typical agricultural formulations extend this base material into potassium salt solutions for foliar or hydroponic delivery, or into talc-based rooting powders for cutting treatment.

This product serves commercial horticulture, floriculture, and forestry nurseries focused on vegetative propagation of herbaceous and woody ornamentals, fruit stock, and high-value vegetables. Application methods include quick-dip in concentrated solution, extended soak, or powder application to wounded stem tissue. Buyers should verify the supplier's batch-specific certificates of analysis for assay confirmation, request material safety data sheets for handling protocols, and confirm whether the 98% figure represents wet-chemical or chromatographic assay methodology. Storage at 2-8 degrees Celsius in amber containers is standard practice to preserve activity.

Xinyi Industrial Co., Ltd is headquartered at Room 604, 1# Bafang Building, 1589 Zhangyang Road, Shanghai 200135, China, placing the company within Shanghai's Pudong-adjacent commercial district rather than in a manufacturing zone. The supplier carries an imported tier classification and a harbor trust tier, with a response rate of 0.00% and zero recorded average response hours in the available data. These signals indicate limited transactional history on this channel, and buyers should treat direct communication verification as essential rather than optional.

The listing presents IBA as a core product line without specifying whether Xinyi Industrial operates as a manufacturer, dedicated exporter, or trading intermediary. No stated certifications, production capacity figures, quality control protocols, or client references appear in the profile. Buyers should request the company's business license, any ISO or GMP certificates claimed, and specific details on batch traceability and analytical capabilities before committing to orders.
