Riboflavin (B2)

Description

1. Product Overview

Riboflavin (Vitamin B2) is a high-purity, water-sol essential micronutrient with CAS number 83-88-5 and molecular weight 376.36 g/mol. Its primary industrial use is as a vitamin fortifier and nutrient supplement in food & beverage, pharmaceutical, animal feed, and nutraceutical manufacturing. The key value proposition is certified USP-grade purity (98.0–102.0% on dry basis) with strict quality control for heavy metals, microbial contamination, and lumiflavin impurities. This product is strategically important in the global market as a critical ingredient for meeting regulatory nutrition labeling requirements and addressing vitamin deficiency programs worldwide.
