Buy Di-tert-butyl Dicarbonate | Premium 99.5% Purity Supplier for USA Pharmaceutical Manufacturers – Fast Delivery from China Factory
Struggling with high prices, inconsistent quality, and delayed shipments for Di-tert-butyl Dicarbonate (Boc2O)? As a trusted supplier to US firms, Shijiazhuang Standard IMP&EXP delivers lab-grade Boc anhydride directly from our powerful factory, slashing your costs by up to 30% while ensuring 99.5% purity and 7-14 day delivery to USA ports.
Di-tert-butyl dicarbonate, commonly known as Boc2O or di-tert-butyl dicarbonate, is a cornerstone reagent in organic synthesis, particularly for pharmaceutical intermediates and peptide manufacturing. With the formula (Boc)2O or C10H18O5, this colorless to pale yellow liquid (CAS: 24424-99-5) serves as a premier protecting group for amines. As your reliable Di-tert-butyl dicarbonate supplier, Shijiazhuang Standard IMP&EXP CO.,LTD. provides industrial-grade Boc anhydride tailored for USA buyers seeking wholesale Di-tert-butyl dicarbonate with guaranteed quality.
In peptide synthesis, Di-tert-butyl dicarbonate introduces the tert-butoxycarbonyl (Boc) group to primary and secondary amines, shielding them from unwanted reactions. This protection is reversible under acidic conditions (e.g., TFA), making it ideal for solid-phase peptide synthesis (SPPS). According to a 2023 report from Grand View Research, the global peptide therapeutics market is projected to reach $58.5 billion by 2028, driving demand for high-purity Boc2O. US manufacturers, facing stringent FDA guidelines, rely on suppliers like us for 99.5%+ purity to avoid synthesis failures that cost up to $50,000 per batch.
Chemically, Di-tert-butyl dicarbonate reacts via nucleophilic attack by amines on its carbonyl, releasing CO2 and tert-butanol. Its boiling point (around 124°C at 20 mmHg) and solubility in organic solvents like DCM, THF, and DMF make it versatile for lab and scale-up production. Density: 1.04 g/cm³; Molecular weight: 218.25 g/mol. We produce it via phosgene-free routes in our state-of-the-art fermentation and crystallization facilities, ensuring eco-friendly compliance with US EPA standards.
Beyond peptides, applications span API synthesis (e.g., sartans, antibiotics), agrochemicals, and fine chemicals. For instance, in atorvastatin production, Boc protection prevents side reactions, boosting yields by 15-20%. Our Di-tert-butyl dicarbonate price is competitive at $25-35/kg for bulk (FOB Tianjin), undercutting Western competitors by 25-40% thanks to our powerful factory capacity of 5,000 MT/year.
Storage requires cool, dry conditions (2-8°C) away from bases and moisture to prevent decomposition. Shelf life: 24 months under proper handling. As a China Di-tert-butyl dicarbonate supplier to USA, we ship in 190kg drums or 25kg cartons, certified for ocean freight to major ports like Los Angeles, New York, and Houston.
Industry data from MarketsandMarkets highlights supply chain vulnerabilities: 35% of US pharma firms report delays in Boc2O procurement due to China's dominance (80% global supply) yet quality concerns. Our USP—OEM/ODM customization, high-speed delivery (7 days to port), and rigorous QC—resolves this. We've exported to USA clients since 2005, supporting firms in New Jersey and California hubs.
LSI terms like Boc anhydride wholesale, tert-butyl pyrocarbonate supplier, and peptide protecting reagent underscore its role. Purity analysis via HPLC (>99.5%), GC for impurities (<0.1% water), and NMR confirms structure. Safety: Handle under fume hood; LD50 >2000 mg/kg (rat, oral)—non-toxic but irritant.
In summary, buying Di-tert-butyl dicarbonate from us means reliable access to this essential reagent. Our 20+ years in pharmaceutical intermediates guarantee compliance with US regs (TSCA-listed). Ready to optimize your synthesis?
Your Biggest Challenges Sourcing Di-tert-butyl Dicarbonate for US Operations
As a purchasing manager, you face relentless pressure to cut costs while maintaining FDA-compliant quality.
- High Prices: Western suppliers charge $50-70/kg, eroding your ROI. Industry avg. markup: 40%.
- Low Quality Risks: Impure Boc2O causes 20-30% yield losses, per ACS studies—$10K+ per failed run.
- Skyrocketing Shipping Costs: Delays from Europe/Asia add $5-10/kg; 45% of US buyers report 4+ week waits (Deloitte 2024).
- Unreliable Supply Chains: China's dominance leads to shortages; 28% disruption rate last year.
- Regulatory Hurdles: Non-compliant batches rejected at customs, halting production.
- Lack of Customization: No OEM options for your specific purity/volume needs.
