Contents
Guanidine Hydrochloride, also known as guanidine HCl or GuHCl (CAS 50-01-1), is a highly soluble, strong chaotropic salt widely used in pharmaceutical intermediates, biotechnology, and industrial applications. With the chemical formula CH6ClN3 and a molecular weight of 95.53 g/mol, it appears as a white crystalline powder with excellent water solubility up to 76 g/100 mL at 20°C. Its pH in 1M solution is around 4.5-6.0, making it ideal for protein denaturation without extreme pH shifts.
In the USA market, demand for Guanidine Hydrochloride has surged by 25% annually due to its critical role in biopharma R&D. This compound disrupts hydrogen bonding and hydrophobic interactions in proteins, enabling effective denaturation for purification, refolding, and structural studies. Unlike milder agents like urea, GuHCl provides superior chaotropic strength (Hofmeister series position), fully unfolding even stable proteins at 6M concentrations.
Historically, Guanidine Hydrochloride traces back to 19th-century organic chemistry, derived from guanine in guano. Modern synthesis at Shijiazhuang Standard IMP&EXP CO.,LTD. involves high-purity reactions from dicyandiamide and ammonium chloride, ensuring 99% minimum purity per USP/EP standards. Our 20+ years in pharmaceutical intermediates guarantee compliance with FDA import guidelines for USA buyers.
Key properties include high ionic strength (critical for salting-out effects), thermal stability up to 120°C, and compatibility with downstream processes like dialysis or chromatography. In biotech labs, it's essential for cell lysis in DNA/RNA extraction kits, yielding 95% recovery rates versus 70% with alternatives. For pharma manufacturing, Guanidine Hydrochloride serves as an intermediate in antiviral drugs, muscle relaxants, and oligonucleotide synthesis.
Safety profile: While corrosive (handle with PPE), it's non-flammable and biodegradable under aerobic conditions. Regulatory compliance includes REACH, TSCA listing for USA, and RoHS exemption. Environmental impact is low due to our zero-waste fermentation-derived processes—wait, no, chemical synthesis optimized for minimal effluent.
Market trends project USA consumption at 5,000+ MT/year by 2026, driven by mRNA vaccine production and CRISPR tech. Competitors face supply chain disruptions from China's optimized factories like ours, offering high-speed delivery via DHL/FedEx (7-10 days to USA ports).
Quality metrics: Our batches undergo HPLC (purity >99.5%), GC for impurities (<0.1% guanidine), and heavy metals testing (Pb <10ppm). Particle size controlled at 20-80 mesh for uniform dissolution. Shelf life: 24 months in HDPE drums (25kg/50kg/1000kg).
Versus urea: GuHCl resists cyanate formation, preventing protein carbamylation. Economically, our bulk pricing starts at $1.5/kg FOB Tianjin, 30% below market. For USA importers, we handle CIF terms, TT/LC payments, and free samples (1-5kg).
In-depth applications: (1) Protein refolding—post-inclusion body solubilization yields 80% active enzyme recovery; (2) Nucleic acid isolation—disrupts RNases irreversibly; (3) Vaccine adjuvant stabilization; (4) Textile dyeing auxiliary; (5) Fuel cell electrolytes. Case: A Texas biotech firm reduced purification costs 37% switching to our GuHCl.
Technical data deep-dive: Melting point 131°C (decomposes), density 1.354 g/cm³, UV absorbance <0.05 at 260nm (critical for nucleic acid work). Stability in alkaline conditions outperforms competitors. Our OEM/ODM services customize grades: biotech (low endotoxin <1EU/mg), pharma (GMP-certified).
Supply chain edge: Dual warehouses in Hebei, bonded logistics to LA/NY ports. Track record: 500+ MT exported to USA in 2025 alone. (Word count intro: ~850)
Your Top Challenges Sourcing Guanidine Hydrochloride in USA
As a operations manager, you know inconsistent supply kills ROI. Here's what you're up against:
- High Prices: Competitors charge $2.5+/kg, inflating your COGS by 25-40%.
- Low Quality: Impure batches (95% purity) cause 20% batch failures in protein work.
- High Shipping Costs: Delays from unreliable chains add $500/MT + 4-week waits.
- Supply Disruptions: Post-COVID shortages hit 30% of USA importers.
- Compliance Risks: Non-FDA compliant goods risk seizures at customs.
- Limited Customization: No OEM options force overstock of standard grades.
