Citric Acid CAS 77-92-9 is one of the most versatile and widely used organic acids in the global food, beverage, pharmaceutical, and industrial sectors. Known chemically as 2-hydroxypropane-1,2,3-tricarboxylic acid, this tricarboxylic acid occurs naturally in citrus fruits like lemons and oranges, from which it was first isolated in 1784 by Carl Wilhelm Scheele. Today, industrial production of Citric Acid CAS 77-92-9 relies on fermentation processes using Aspergillus niger molds on substrates like corn starch or molasses—exactly the method employed in our two dedicated fermentation departments at Shijiazhuang Standard IMP&EXP.

The CAS number 77-92-9 uniquely identifies this anhydrous form of citric acid, distinguishing it from monohydrate variants (CAS 5949-29-1). Its molecular formula is C₆H₈O₇, with a molecular weight of 192.12 g/mol. Physically, Citric Acid CAS 77-92-9 appears as odorless, colorless crystals or a white crystalline powder, highly soluble in water (up to 59g/100ml at 20°C) and slightly soluble in ethanol. This solubility profile makes it ideal for aqueous formulations in your production lines.

In terms of functionality, Citric Acid CAS 77-92-9 excels as an acidulant, providing a sharp tartness at concentrations as low as 0.3-0.5% in beverages. It lowers pH effectively— from 7 to around 2.2 in a 1% solution—enhancing microbial stability and preserving freshness. Beyond acidification, it chelates metal ions, preventing oxidation and enzymatic browning in fruits and vegetables. For instance, in canning, adding 0.1-0.3% Citric Acid CAS 77-92-9 extends shelf life by inhibiting Clostridium botulinum growth.

Market data underscores its demand: Global citric acid production exceeded 2.2 million metric tons in 2023, per Grand View Research, with USA imports alone surpassing 200,000 tons annually. The food and beverage segment dominates at 70% usage, followed by pharmaceuticals (15%) for effervescent tablets and syrups. In pharma, Citric Acid CAS 77-92-9 buffers solutions to pH 3-6, crucial for vitamin C stability in oral liquids. Industrially, it's a key component in detergents (as a builder replacing phosphates) and cosmetics (pH adjuster in shampoos).

Regulatory compliance is paramount for US buyers. Our Citric Acid CAS 77-92-9 meets USP-NF, FCC, BP, EP, and JP pharmacopeia standards, affirming its GRAS (Generally Recognized as Safe) status by the FDA (21 CFR 184.1033). It's also Halal, Kosher, and GMO-free, verified by independent labs. Purity levels reach 99.5-99.9%, with low heavy metals (<1ppm arsenic, <0.5ppm lead), ensuring it passes your incoming inspections seamlessly.

Production at scale: Our facility ferments high-quality corn starch, yielding crystalline citric acid via decolorization, crystallization, and drying. This yields consistent batch-to-batch quality, unlike variable imports from fragmented suppliers. Economically, Citric Acid CAS 77-92-9 pricing hovers at $800-1,200/MT FOB China (2026 forecast), but our direct factory pricing undercuts competitors by 20-25% through optimized supply chains.

Environmental impact: Citric acid is biodegradable (OECD 301B >60% in 28 days), aligning with your sustainability goals. In 2026, with USA tariffs on Chinese chemicals stabilizing post-2024 reviews, sourcing Citric Acid CAS 77-92-9 from verified exporters like us minimizes risks. We've shipped over 5,000 MT annually to USA ports like Long Beach and New York, with zero quality rejections reported.

Technical deep dive: Citric acid participates in the Krebs cycle biologically, highlighting its safety. Thermally stable up to 175°C (decomposes above), it's perfect for baking powders (releasing CO₂ with bicarbonates). In animal feed, at 0.5-2%, it improves nutrient absorption, reducing FCR by 5-10% in poultry trials (Journal of Animal Science, 2022). For cross-border e-commerce sellers, our OEM/ODM services label packs from 25kg bags to 1MT IBCs, ready for Amazon FBA.

Comparing forms: Anhydrous CAS 77-92-9 is preferred for dry blends (99% market share in powders), while monohydrate suits liquids. Our stocks ensure 500MT availability monthly. Pain points like high moisture in inferior products? Our <0.1% H₂O spec prevents caking.
