As a B2B consumer, whether you are in pharmaceutical research, the food industry, or require analytical standards, understanding the properties, uses, and sourcing of this compound is crucial for successful procurement and application.

This article aims to provide a comprehensive overview of Cyanidin-3-O-arabinoside chloride, covering its chemical and physical characteristics, its diverse applications, and practical advice on how to source it reliably from manufacturers, particularly those in China.

Chemical and Physical Properties

Cyanidin-3-O-arabinoside chloride (molecular formula C20H19ClO10, molecular weight ~454.81 g/mol) typically presents as a dark red powder. Its structure is based on the cyanidin aglycone, which is glycosylated with arabinose at the 3-position, and it exists as a chloride salt. These structural features are key to its observed properties:

  • Antioxidant Activity: Like many flavonoids and anthocyanins, Cyanidin-3-O-arabinoside chloride is a potent antioxidant. It functions by scavenging reactive oxygen species (ROS) and free radicals, thereby protecting cells from oxidative damage. This property is of great interest in pharmaceutical research and the development of health-promoting supplements.
  • Color Properties: As an anthocyanin, it is a natural pigment. Its intense red hue makes it valuable in the food and cosmetic industries as a natural colorant, offering an alternative to synthetic dyes. The color intensity and shade can be influenced by pH and other environmental factors.
  • Solubility: It is generally soluble in polar solvents such as methanol, ethanol, and DMSO, which is important for its use in research assays and for preparing solutions.

Key Applications Across Industries

The versatility of Cyanidin-3-O-arabinoside chloride lends itself to several key applications:

1. Pharmaceutical and Biochemical Research: It is widely used as a research chemical to study the mechanisms of antioxidant action, cellular protection against oxidative stress, anti-inflammatory effects, and potential therapeutic benefits in various disease models. Its role as an analytical standard in HPLC and other chromatographic methods for quantifying anthocyanins in biological samples or plant extracts is also significant.

2. Food and Beverage Industry: As a natural colorant, it can impart vibrant red to purple shades in products like juices, yogurts, candies, and jams. Its use aligns with the growing consumer demand for clean-label products.

3. Nutraceuticals: Given its antioxidant properties, it is explored as an ingredient in dietary supplements aimed at promoting general health, cardiovascular wellness, and combating age-related decline.

Sourcing Cyanidin-3-O-arabinoside Chloride: Manufacturer and Supplier Insights
