CAS 1137-42-4, chemically known as 2-Amino-5-nitrobenzoic acid, is a critical pharmaceutical intermediate widely used in the synthesis of advanced APIs, dyes, and agrochemicals. With the molecular formula C7H6N2O4 and a molecular weight of 182.14 g/mol, this yellow to light brown crystalline powder plays a pivotal role in organic synthesis due to its nitro and amino functional groups, which enable versatile reactions like diazotization, reduction, and coupling.

In the pharmaceutical industry, buying CAS 1137-42-4 in bulk is essential for manufacturers producing anti-inflammatory drugs, antimicrobial agents, and complex azo compounds. Its high reactivity makes it ideal for creating intermediates in the production of nitro-substituted benzoic acid derivatives, which are foundational in modern drug discovery. According to industry reports from Grand View Research (2025 projection), the global demand for nitrobenzoic acid derivatives is expected to grow at a CAGR of 5.8% through 2030, driven by rising needs in personalized medicine and specialty chemicals.

What sets CAS 1137-42-4 apart is its stability under standard storage conditions (2-8°C, protected from light), ensuring minimal degradation during shipping and storage. High-purity grades (>99%) are crucial to avoid side reactions in downstream processes, where even trace impurities can lead to batch failures costing thousands in rework. At Global Technology Co., Ltd, we source this from GMP and DMF-certified partners, guaranteeing batch-to-batch consistency verified by HPLC, NMR, and MS analysis.

Historically, 2-Amino-5-nitrobenzoic acid has been employed in the synthesis of fluorescent probes for bioimaging and as a building block for herbicides. In 2026, with supply chain disruptions easing post-2025 global logistics reforms, procurement teams in the USA and English-speaking regions are prioritizing suppliers like us who offer scalable quantities from grams to metric tons. Our closed-loop cooperation with university labs ensures custom purity levels up to 99.9%, tailored to your R&D or commercial needs.

Sourcing CAS 1137-42-4 wholesale involves navigating regulatory hurdles like REACH compliance for EU exports and FDA DMF filings for US pharma. We handle all documentation, including CoA (Certificate of Analysis), MSDS, and stability data, so your compliance team can focus on innovation. Typical applications include:

Pharma APIs: Key precursor for nitroaniline derivatives in oncology drugs.
Dyes & Pigments: Azo coupling agent for high-fastness colorants.
Agrochem: Intermediate for selective herbicides.
Research: Probes in fluorescence microscopy.

Pricing volatility has plagued buyers—spot prices fluctuated 25% in 2025 due to raw material shortages. Our vertically integrated supply chain from Henan Province stabilizes costs at $45-65/kg for 99% purity, 30% below competitors. Delivery times? 7-14 days to USA via DHL/FedEx, with FOB/CIF terms flexible for your Incoterms.

As a B2B buyer, you appreciate the technical edge: Our product exhibits mp 228-232°C, solubility in DMSO/ethanol, and low moisture (<0.5%). We support OEM/ODM for modified specs, like deuterated variants for NMR standards. In 2026, with BERT-optimized search favoring EEAT content, partnering with proven suppliers like Global Technology ensures your procurement aligns with Google's top-ranking reliability signals.

Core Pain Points When Sourcing CAS 1137-42-4 for Your Operations

As a purchasing manager or technical director, you face relentless pressure to optimize costs while maintaining quality. Here's how unreliable suppliers derail your goals:

High Prices Eating ROI: Competitors charge $80-120/kg, but hidden fees inflate totals by 40%. Scenario: A mid-size pharma firm lost $50K last quarter on overpriced batches.
Low Quality & Impurities: Sub-98% purity causes 15-20% yield loss in synthesis. Data: IQVIA reports 28% of intermediates fail purity specs from non-GMP sources.
Skyrocketing Shipping Costs: Delays from China average 30 days, with duties adding 25%. Your ops team waits, production halts.
Inconsistent Supply: Stockouts during peak demand spike MOQs, forcing panic buys at premiums.
Compliance Nightmares: Missing DMF/CoA leads to FDA holds, delaying launches by months.
Poor Service: No customization, slow responses—your C-level demands better.
