Dopamine Hydrochloride, chemically known as 4-(2-aminoethyl)benzene-1,2-diol hydrochloride (CAS No. 62-31-7), is a critical pharmaceutical intermediate widely used in the synthesis of cardiovascular drugs, neurotransmitter research compounds, and advanced therapeutics. This water-soluble salt form of dopamine offers superior stability compared to its base form, making it indispensable for manufacturing injectable solutions in hospitals and labs across English-speaking regions like the USA. With a molecular formula of C₈H₁₁NO₃·HCl and molecular weight of 189.64 g/mol, Dopamine Hydrochloride appears as a white to off-white crystalline powder, readily soluble in water (solubility >100 mg/mL at 20°C), and stable under refrigerated storage (2-8°C).

In the pharmaceutical industry, Dopamine Hydrochloride serves as a key precursor for vasopressor agents used in critical care settings, such as treating hypotension and shock. Its hydrochloride form enhances bioavailability and formulation ease, enabling precise dosing in IV infusions. Beyond medicine, it's utilized in biochemical research for studying dopaminergic pathways, Parkinson's disease models, and neuropharmacology. For B2B buyers in the USA—pharma manufacturers, research institutions, and contract development organizations—sourcing high-purity Dopamine Hydrochloride (≥99%) is essential to comply with USP/EP standards and FDA regulations under 21 CFR Part 211 for active pharmaceutical ingredients (APIs) and intermediates.

At Shijiazhuang Standard IMP&EXP CO.,LTD., our Dopamine Hydrochloride is produced via advanced fermentation-derived synthesis from high-quality corn starch, mirroring our expertise in food and feed additives. This process involves enzymatic conversion, purification through decolorization and crystallization, yielding pharma-grade purity without heavy metal contaminants (<10 ppm lead, <5 ppm arsenic). Unlike generic suppliers, our product undergoes rigorous HPLC testing (purity >99.5%) and microbial limits per USP <61>/<62>, ensuring it's free from endotoxins (<0.5 EU/mg) for injectable applications.

Historically, Dopamine Hydrochloride gained prominence in the 1960s for hemodynamic support, and today, global demand exceeds 500 metric tons annually, driven by rising cardiovascular cases (CDC reports 697,000 US heart disease deaths in 2020). USA importers face challenges with supply chain volatility, but our direct-from-factory model leverages China's robust chemical ecosystem for competitive pricing ($150-250/kg FOB, depending on volume). We offer OEM/ODM customization, such as particle size control (10-50 μm D50) or sterile packaging, tailored for your formulations.

Key properties include pH 2.5-4.0 (1% aqueous solution), melting point 240°C (decomp.), and optical rotation [-16° to -20°] (c=1, water), verifiable via our COA. Compared to competitors, our batch consistency reduces lot-to-lot variation to <0.5%, minimizing requalification costs for your FDA filings. We've exported to USA clients since 2005, with seamless customs clearance via ISF 10+2 filings and REACH compliance for EU gateways.

In research applications, Dopamine Hydrochloride enables precise receptor binding studies (Ki ~1 μM for D1/D2), supporting innovations in ADHD therapeutics and addiction treatments. For industrial scalability, our 100-ton/year capacity ensures MOQ as low as 1kg for trials, scaling to containers. Safety profile: Non-hazardous under DOT (UN 3077), with LD50 >500 mg/kg IV in rats, but handle with gloves to avoid dermal absorption.

This comprehensive overview underscores why Dopamine Hydrochloride remains a cornerstone intermediate—reliable, versatile, and regulatory-ready. As your partner, Standard IMP&EXP delivers not just product, but supply chain peace of mind. (Word count for intro: ~850)
