Product Description

Product Description

Citric Acid CAS 77-92-9Citric Acid, a pivotal organic carboxylic acid, is a versatile raw material widely utilized across food, chemical, and pharmaceutical industries. Naturally occurring in citrus fruits (such as lemons and oranges), it is now predominantly produced via large-scale microbial fermentation (typically using Aspergillus niger), making it one of the highest-volume organic acids globally.
With the molecular formula C6H8O7 and a molar mass of 192.12 g·mol¹, citric acid is classified under CAS number 77-92-9 and EINECS number 201-069-1. Under standard conditions (23°C), the anhydrous form appears as a colorless crystalline solid or white crystalline powder, odorless, with a strong, characteristic acidic taste; its monohydrate counterpart is also a white crystalline solid, both exhibiting excellent solubility in water.
Citric acid's unique molecular structure—featuring three carboxyl groups and a hydroxyl group (as 2-hydroxypropane-1,2,3-tricarboxylic acid)—endows it with superior acidity, chelating properties, and biocompatibility. These attributes drive its widespread adoption: it serves as a sour agent, preservative, and flavor enhancer in food & beverages; a pH regulator and chelating agent in cosmetics and personal care products; a cleaning and descaling agent in industrial applications; and an excipient in pharmaceutical formulations, solidifying its role as a foundational material across diverse sectors.Specification

Core Product Advantages1.Superior Purity and StabilityEmploying advanced Aspergillus niger microbial fermentation and precision crystallization technologies, Citric Acid (CAS 77-92-9) achieves a purity level of 99.5% or higher, with pharmaceutical-grade products reaching 99.9%. Strict adherence to ISO 9001 and HACCP quality management systems ensures batch-to-batch variation is controlled within 0.3%, providing reliable performance guarantees for high-end food, pharmaceutical, and industrial applications. The stable carboxylic acid molecular structure enables a 24-month shelf life when stored in cool, dry conditions, significantly reducing material waste risks for users.2.Excellent Coloring Performance & Food SafetyCitric Acid exhibits mild yet long-lasting acidity and strong metal chelating capacity, thanks to its tri-carboxyl molecular structure. It can efficiently regulate pH levels (ideal for food flavor enhancement) and sequester metal ions (effective for industrial descaling and food preservation). Unlike harsh inorganic acids, it maintains good compatibility with most ingredients—without altering product flavors (in food) or causing material corrosion (in industrial use)—making it a safer, more versatile functional additive.3.Flexible Customization and Supply SecurityManufacturers offer customized production services for Citric Acid, including multiple purity grades (food/industrial/pharmaceutical grade) and flexible packaging specifications (1kg/bottle, 25kg/woven bag, 1000kg/bulk bag) to meet diverse R&D and mass production needs. With an annual production capacity exceeding 5,000 tons, the supply chain ensures stable material provision—including dedicated production lines for large-volume customers—effectively avoiding supply chain disruptions in downstream production.Application

1. Food and Beverage Industry
In the food and beverage sector, Citric Acid (CAS 77-92-9) acts as a primary sour agent, preservative, and flavor enhancer. It is widely used in carbonated drinks, fruit jams, candies, and canned fruits: its mild, citrus-like acidity balances sweetness to enhance flavor layers, while its chelating properties sequester metal ions (e.g., iron, copper) to prevent color fading and nutrient degradation. In processed meats and dairy products, it extends shelf life by inhibiting microbial growth—all while meeting global food safety standards (e.g., FDA, EU Food Grade). Unlike synthetic sour agents, citric acid (naturally derived from citrus fermentation) offers a more authentic, palatable taste profile, making it a staple in both mass-market and premium food formulations.
2. Industrial Cleaning & Water Treatment
Citric Acid is a high-performance chelating agent and descaling material in industrial settings. In boiler and pipeline maintenance, it dissolves limescale (calcium/magnesium deposits) via carboxyl-metal ion complexation—replacing harsher inorganic acids (e.g., hydrochloric acid) to avoid equipment corrosion and surface damage. In water treatment systems, it stabilizes pH levels and reduces heavy metal contamination, supporting compliance with environmental discharge regulations. It is also a key ingredient in eco-friendly household detergents: its chelating action boosts stain-removal efficiency while protecting fabric fibers, making it suitable for delicate textiles (e.g., wool, silk).
3. Pharmaceutical & Nutraceutical Production
In pharmaceutical manufacturing, Citric Acid functions as a pharmaceutical excipient (buffer, disintegrant, and solubilizer) for oral tablets, capsules, and injectable formulations. Its mild acidity regulates pH in drug solutions to enhance active ingredient stability (e.g., for vitamin C or antibiotic preparations), while its disintegrant properties ensure rapid tablet breakdown in the gastrointestinal tract for improved bioavailability. It also serves as a precursor in the synthesis of nutraceuticals (e.g., effervescent vitamin supplements) and meets strict pharmacopeial standards (USP, EP, BP) for purity and biocompatibility, making it safe for medical applications.Company Profile
