What is D-Ribose CAS 50-69-1?

D-Ribose is a naturally occurring five-carbon monosaccharide supplied as a white crystalline powder. It has the molecular formula C5H10O5, a molecular weight of 150.13 g/mol, and the EINECS number 200-059-4.

Is D-Ribose the same as ribose or D-ribofuranose?

Yes. D-Ribose, D-ribofuranose, and D-ribopyranose describe the same monosaccharide depending on whether it is shown in the open-chain or cyclic form. The names are used interchangeably for the ingredient identified by CAS 50-69-1.

What are the main food and supplement uses of D-Ribose?

It is used in dietary supplements, sports nutrition products, energy drinks, and functional foods. In these applications D-Ribose supports cellular energy formulations and provides a mildly sweet, readily soluble carbohydrate source.

What role does D-Ribose play in biochemical and pharmaceutical manufacturing?

D-Ribose is an important substrate for nucleotide and coenzyme synthesis, and an intermediate in products such as riboflavin, nucleosides, and selected APIs. It is also used as a carbon source in fermentation media and cell-culture systems.

What grade and purity is D-Ribose normally available in?

Food grade, USP grade, and biochemical grade are common, with food-grade material frequently meeting FCC requirements. Commercial powder specifications are often around 97.0-102.0%, with the appropriate grade selected for the intended application.

How should D-Ribose powder be stored and handled?

Store it in tightly closed containers in a cool, dry, well-ventilated area because the powder is hygroscopic and sensitive to moisture. Avoid humid conditions and keep packaging intact to preserve flowability, stability, and product quality.

D-Ribose CAS 50-69-1

D-Ribose is a naturally occurring pentose sugar used in food, nutraceutical, and biochemical formulations. Supplied as crystalline powder with standard packaging and documentation support including COA, TDS, and SDS.

Packaging

D-Ribose is typically supplied as a crystalline powder packed in moisture-resistant bags or fiber drums with inner liners to protect against humidity and contamination. Packaging is designed to maintain product stability and flowability during transport and storage. Packaging formats can be arranged according to order volume and logistics requirements.

Storage

Store in a cool, dry, and well-ventilated area. Keep containers tightly sealed to prevent moisture absorption, as the product is hygroscopic. Avoid exposure to humid conditions and maintain packaging integrity during storage and transportation.
