Import Alarelin Acetate — Buy in Bulk from Supplier in China

Alarelin acetate from Shanghai Hanhong Chemical is a synthetic decapeptide analogue of gonadotropin-releasing hormone (GnRH), supplied as the acetate salt with a stated purity of 98 percent by HPLC. The molecular formula is C62H78N16O13S, indicating a modified luteinising hormone-releasing hormone sequence with a molecular weight typically near 1227.4 g/mol for the free base and somewhat higher for the acetate complex. This peptide functions as a potent GnRH agonist, stimulating initial pituitary gonadotropin release before downregulating receptor sensitivity with sustained administration, a mechanism exploited in reproductive endocrinology research and fertility protocol development.

The 98 percent HPLC purity specification refers to area percent purity by reversed-phase high-performance liquid chromatography, a standard analytical method for peptide quality assessment; buyers should request the specific HPLC method parameters, including column chemistry, mobile phase composition, and gradient programme, to assess method suitability. The acetate counterion is introduced during solid-phase peptide synthesis and final lyophilisation, affecting solubility and stability profiles. Shanghai Hanhong Chemical indicates availability in multiple quantities, though no specific pack sizes, vial configurations, or fill weights appear in the source data. Storage and handling protocols for alarelin acetate typically require lyophilised powder storage at -20 degrees Celsius with protection from moisture and light.

Applications span pharmaceutical research into endometriosis, uterine fibroids, precocious puberty, and assisted reproductive technology protocols, as well as veterinary oestrus synchronisation studies. The supplier's profile does not specify manufacturing facility GMP status, whether the peptide is produced by solid-phase synthesis or recombinant methods, or whether endotoxin levels are controlled. Buyers should confirm with Shanghai Hanhong Chemical the specific salt form stoichiometry, whether the 98 percent purity accounts for acetate content, and whether batch-specific certificates of analysis include mass spectrometry confirmation, amino acid analysis, and endotoxin testing results.

Shanghai Hanhong Chemical, Co., Ltd is headquartered at Room 206, Zenghe Building, 245 Jiachuan Road, Xuhui District, Shanghai 200237, China, placing it within Shanghai's established chemical and pharmaceutical research district. The company holds a harbor trust tier with imported supplier classification, though its response rate is recorded at 0.00 percent with zero average response hours, indicating no measurable buyer communication through the platform. No factory ownership details, GMP certification status, or manufacturing floor space are disclosed in the available profile.

The source description mentions ISO and SGS certifications in a generic manner, but no certificate numbers, scopes, or accreditation bodies are specified; buyers must independently verify whether these apply to Shanghai Hanhong Chemical's peptide operations or to unrelated business lines. The company positions alarelin acetate for research and pharmaceutical manufacturing applications, yet the profile does not clarify whether production occurs in-house or through contracted synthesis partners. What the listing omits is significant: no US FDA drug master file number, no European EDMF/CEP reference, and no indication of peptide cGMP compliance are provided.
