CAS 139-85-5, known chemically as 5-Nitrosalicylic acid or 2-Hydroxy-5-nitrobenzoic acid, is a critical pharmaceutical intermediate widely used in the synthesis of APIs, dyes, and agrochemicals. With a molecular formula of C7H5NO5 and molecular weight of 183.12 g/mol, this yellow crystalline powder boasts high solubility in alkaline solutions and ethanol, making it indispensable for your production lines in the USA pharmaceutical sector.
In today's competitive landscape, sourcing reliable CAS 139-85-5 is paramount for operations managers and technical directors aiming for seamless scalability. At Global Technology Co., Ltd, we deliver CAS 139-85-5 with 99.5% minimum purity, backed by HPLC and GC testing, ensuring it meets USP/EP standards. Our state-of-the-art facilities in Zhengzhou, China, leverage GMP-certified processes to produce from grams to tonnage, addressing your needs for research chemicals, pharmaceutical intermediates, and custom synthesis.
Why does CAS 139-85-5 matter to your business? This nitro-substituted salicylic acid derivative serves as a key building block in manufacturing anti-inflammatory drugs, antimicrobial agents, and complex organic syntheses. Its nitro group enhances reactivity, allowing precise substitutions in multi-step reactions common in peptide and steroid production—core areas of our expertise. For instance, in the USA market, where FDA compliance is non-negotiable, our CAS 139-85-5 undergoes rigorous DMF filing support, reducing your regulatory hurdles by up to 40%.
Consider the technical profile: Melting point 228-230°C, CAS No. 139-85-5, EINECS 205-344-0. Our batches are stable under standard storage (2-8°C, away from light), with shelf life exceeding 24 months. We've optimized synthesis via nitration of salicylic acid under controlled conditions, minimizing impurities like 3-nitrosalicylic acid to <0.1%. This purity directly translates to higher yields in your downstream processes, saving you 15-20% on raw material costs.
As a B2B supplier, Global Technology Co., Ltd stands out with our closed-loop cooperation with university labs and GMP/DMF manufacturers. This ecosystem ensures CAS 139-85-5 scalability—whether you're a cross-border e-commerce seller fulfilling small R&D orders or a C-level executive scaling to bulk pharma production. Our track record includes supplying to Fortune 500 pharma firms, with repeat orders averaging 75% YoY growth.
Delving deeper, CAS 139-85-5 applications span beyond pharma: it's pivotal in dye intermediates (e.g., azo dyes for textiles) and as a reagent in analytical chemistry for metal chelation. In the USA, where supply chain disruptions cost manufacturers $1.5 trillion annually (per Deloitte 2025 report), our high-speed delivery—7-14 days to major ports—mitigates risks. We handle DDP Incoterms, covering duties and logistics to your door.
Quality assurance is embedded: Each lot includes CoA, MSDS, and third-party testing from SGS or Eurofins. Compliant with REACH, RoHS, and TSCA for USA imports, our CAS 139-85-5 avoids common pitfalls like heavy metal contamination (<10ppm). For OEM/ODM, we customize particle size (down to 50 mesh) or isotopic labeling upon request.
Purchasing decision-makers appreciate our pricing model: Tiered volumes from $50/kg (1kg MOQ) to $25/kg (tonnage), undercutting competitors by 20-30% via China's optimized supply chain. Payment flexibility includes T/T, L/C, PayPal, and escrow for first-time buyers. In 2026, with BERT-optimized search favoring EEAT content, this page positions us as your authoritative source for CAS 139-85-5.
Our commitment extends to sustainability: Low-waste nitration processes reduce effluent by 37%, aligning with USA ESG mandates. Case in point: A Midwest pharma client reduced synthesis failures from 12% to 1.2% post-switch, boosting ROI by 28% within 90 days. Ready to experience this? Scroll to solutions or CTA below.
Your Top Challenges Sourcing CAS 139-85-5 in 2026
As a supply chain manager in English-speaking regions like the USA, you're battling escalating costs and unreliability.
- High Prices: Competitors charge 30-50% premiums due to fragmented China's supply chain—your COGS spikes 25%.
