Import Brassinolide — Buy in Bulk from Supplier in China

Hangzhou Xiaoyong Biotechnology Co., Ltd. supplies brassinolide, a brassinosteroid plant growth regulator with systematic name 2α, 3α, 22(R),23(R)-tetrahydroxy-24(S)-methyl-B-homo-7-oxa-5α-cholestan-6-one and CAS number 72962-43-7. This product is offered as a white to off-white powder with minimum 0.1 percent active ingredient content. The molecular formula is C28H48O6 with molecular weight 480.7 g/mol, placing it within the standard synthetic brassinosteroid class used for agricultural enhancement.

The formulation specifies maximum 5.0 percent moisture content and pH range 4.0-7.0, indicating moderate stability under normal storage but hygroscopicity risk above threshold humidity. Brassinolide functions by promoting cell elongation and division, enhancing photosynthetic efficiency, and improving stress tolerance in crop plants. Typical application rates range from 0.01 to 0.1 ppm in foliar sprays, though exact concentration depends on crop species, growth stage, and formulation compatibility. The active ingredient is thermolabile above 60°C and degrades under strong alkaline conditions.

Primary buyers include agrochemical formulators, fertiliser blenders, and large-scale agricultural operations seeking yield enhancement or stress mitigation. The product serves as a technical grade active ingredient requiring further dilution and formulation before field application. Regulatory status varies by jurisdiction; buyers in the EU, North America, and Australasia should confirm registration acceptance and maximum residue limits. Trade terms, MOQ, and lead time require direct confirmation with Hangzhou Xiaoyong Biotechnology Co., Ltd., as do analytical certificates and batch-specific COA availability.

Hangzhou Xiaoyong Biotechnology Co., Ltd. is headquartered in Hangzhou, Zhejiang Province, China, a region with established biotechnology and fine chemical manufacturing infrastructure. The supplier holds a harbor trust tier, indicating baseline marketplace verification. The response rate shows 0.00 percent with zero average response hours, suggesting buyers should establish communication channels with explicit follow-up protocols. The supplier address data is minimal, with country-level confirmation only.

The company profile does not disclose GMP certification status, manufacturing facility scale, R&D capacity, export licence specifics, or existing distribution partnerships. The product description provides chemical identity and basic specification parameters without manufacturing method (chemical synthesis versus extraction), impurity profile, or stability study data. Buyers should request detailed COA, manufacturing flow chart, and quality management system documentation before procurement commitment.
