从China供应商批发进口5-Aminolevulinic Acid Hydrochloride — FOB条款

5-Aminolevulinic Acid Hydrochloride (5-ALA HCl) from Zhenyibio Technology Inc. is a crystalline amino acid derivative with the molecular formula C5H10ClNO3 and a molecular weight of 167.59 g/mol. The material is supplied as a white to pale yellow crystalline powder with a declared purity of 98.0% to 102.0%, meeting the tight assay window expected for cosmetic and photodynamic therapy applications. Its CAS number is 5451-09-2 and EINECS number is 226-679-5, identifiers that trace back to established chemical inventories for this protoporphyrin precursor.

The compound functions as a direct precursor in the heme biosynthesis pathway, where exogenous administration drives intracellular accumulation of protoporphyrin IX, a potent photosensitizer. In cosmetic formulations, this mechanism underpins its use for skin rejuvenation and photoprotection, while in clinical settings it enables photodynamic diagnosis and therapy of certain lesions. The hydrochloride salt form improves aqueous solubility and stability versus the free base, a typical consideration for formulation chemists working with ALA derivatives. Standard storage conditions for this hygroscopic powder involve tight containers away from light and moisture to prevent degradation of the labile amino-ketone structure.

Primary buyers include cosmetics manufacturers developing anti-aging or brightening lines, contract formulation labs creating private-label skincare, and research groups investigating porphyrin-mediated photodynamic effects. The material serves both the personal care and biomedical supply chains from Zhenyibio's base in Xi'an, Shaanxi Province. Importers should confirm with the supplier whether grades are available separated by endotoxin content or particle size distribution, as these parameters matter for injectable versus topical end uses.

Zhenyibio Technology Inc. operates from No.29 Kejiliulu in the Gaoxin District of Xi'an City, Shaanxi Province, China, placing it within a major inland hub for pharmaceutical and biotechnology manufacturing. The company's listing carries a harbor trust tier, which indicates a baseline level of platform verification, though the response rate shows 0.00% with an average response time of zero hours, a signal that prospective buyers should treat with appropriate caution. No information is provided about the year of establishment, number of employees, annual revenue, or specific manufacturing certifications held by the facility.

The supplier's profile focuses on the chemical identity and application domains of 5-Aminolevulinic Acid Hydrochloride rather than company history or capacity metrics. The address suggests access to Xi'an's developed logistics infrastructure for domestic distribution, though international buyers will need to clarify export licensing, customs registration, and whether the site operates under GMP or ISO conditions. The absence of disclosed client references, production volume, or R&D capabilities means that due diligence on manufacturing standards and batch consistency falls to the importer.
