Description

Steviol CAS NO 471-80-7 is the aglycone diterpenoid core of the steviol glycosides, which are the natural sweet-tasting compounds found in the leaves of the *Stevia rebaudiana* plant. This compound serves as the critical chemical backbone for the production of high-intensity, zero-calorie natural sweeteners. It is an essential intermediate and reference standard for manufacturers and researchers in the food & beverage, nutraceutical, and pharmaceutical industries seeking to develop or analyze next-generation sugar alternatives.

Application

• Reference Standard for Steviol Glycoside Analysis: Used as a primary standard in HPLC and LC-MS methods for the identification and quantification of stevioside, rebaudioside A, and other related sweeteners in raw materials and finished products.
• Biocatalytic & Synthetic Intermediate: Serves as a key starting material or intermediate in the enzymatic and chemical synthesis of various high-purity steviol glycosides.
• Food & Beverage R&D: Employed in research to study the metabolic pathways, stability, and sensory properties of stevia-based sweeteners.
• Pharmaceutical Research: Investigated for potential therapeutic properties, including as a precursor for novel drug candidates, due to its unique diterpenoid structure.
• Quality Control & Regulatory Compliance: Essential for laboratories to validate analytical methods and ensure compliance with food safety regulations (e.g., JECFA, FCC, EU specifications) for stevia products.
• Academic & Industrial Research: Used in studies focusing on plant biochemistry, natural product chemistry, and the development of novel sweetening systems.
