从China供应商批发进口Acetyl-L-Carnitine, Cas No.5080-50-2 — FOB条款

Acetyl-L-carnitine hydrochloride from Gihi Chemicals Co., Limited is supplied under product code GIHI-10 as a fine chemical with CAS number 5080-50-2 and molecular formula C9H18ClNO4. The compound has a molecular weight of 239.7 g/mol, a specific rotation of -29 degrees (c=1, H2O), and decomposes at 194 degrees C without a true melting point under standard conditions. This material is the hydrochloride salt of O-acetyl-L-carnitine, an esterified derivative of L-carnitine that is distinguished from standard L-carnitine by the acetyl group at the hydroxyl position, altering its lipophilicity and tissue distribution profile. The supplier is based in Hangzhou, Zhejiang Province, within one of China's densest concentrations of fine chemical and pharmaceutical research enterprises.

The hydrochloride salt form ensures enhanced aqueous solubility and stability during formulation, with the specific rotation of -29 degrees confirming the (R)-configuration at the chiral centre. For this compound class, typical quality parameters include assay by non-aqueous titration or HPLC, related substances by HPLC with limits for L-carnitine, acetyl chloride, and other process impurities, and loss on drying typically not exceeding 0.5% at 105 degrees C. The decomposition behaviour at 194 degrees C is characteristic of quaternary ammonium salt structures where thermal degradation precedes melting, a property that informs processing temperature limits during tableting and encapsulation. Standard synthetic routes involve acetylation of L-carnitine with acetic anhydride or acetyl chloride followed by HCl treatment, with residual acetic acid and unreacted starting materials requiring rigorous control.

Buyers of this material include pharmaceutical development companies, contract research organisations, and nutraceutical manufacturers formulating products for cognitive health, male fertility support, and peripheral neuropathy indications. The compound is typically incorporated at 500-1500 mg per serving in dietary supplements艰苦奋斗 supplements, or used as a reference standard and analytical reagent in pharmacological research. Gihi Chemicals Co., Limited should be asked to confirm the available grades (pharmaceutical, food, or reagent grade), batch sizes, packaging configurations, and whether they provide stability-indicating assay data. The response rate of 0.00% means direct outreach is essential to establish commercial terms, technical support availability, and the supplier's capacity for custom synthesis or isotopically labelled analogues if required for research applications.

Gihi Chemicals Co., Limited operates from No 7, Huacai International Building, Den, Hangzhou, Zhejiang Province, China, a location within Hangzhou's well-developed chemical industry zone. The company holds a Harbor trust tier. The response rate is shown as 0.00% with 0 average response hours, which indicates that marketplace-mediated communication has not been established, and buyers must pursue direct channels for reliable contact. The listing presents this supplier as a fine chemical specialist with systematic product numbering (GIHI-10) and detailed synonym coverage, suggesting organisational investment in chemical informatics and catalogue management.

No information is provided in the listing regarding Gihi Chemicals Co., Limited's year of establishment, number of employees, annual turnover, manufacturing facility ownership, GMP compliance, ISO certification, or named clients. The product data is confined to the single item GIHI-10 with its physicochemical constants. Buyers should independently verify the company's business registration with the Hangzhou Municipal Administration for Market Regulation, request their high-tech enterprise or export licence status, and ask for a facility audit report or third-party verification if considering them for pharmaceutical-grade supply. The absence of stated quality certifications means each technical and compliance claim must be substantiated through direct due diligence and batch-specific documentation.
