 D(+)-Sucrose (CAS NO.57-50-1) can be widely used in food, cosmetics, and medicine, and is also used for the analysis of standard testing. It has been used as the standard for organic elemental analysis, too.

Reported in EPA TSCA Inventory. EPA Genetic Toxicology Program.

Mildly toxic by ingestion. An experimental teratogen. Mutation data reported. Vigorous reaction with nitric acid or sulfuric acid (forms carbon monoxide and carbon dioxide). When heated to decomposition it emits acrid smoke and irritating fumes.

 D(+)-Sucrose , its cas register number is 57-50-1. It also can be called alpha-D-Glucopyranosyl beta-D-fructofuranoside ; beta-D-Fructofuranose-(2-1)-alpha-D-glucopyranoside ; Sucrose ; Saccharose ; and alpha-D-Glucopyranosyl beta-D-fructofuranoside . It is hazardous, so the first aid measures and others should be known. Such as: When on the skin: Should flush skin with plenty of water immediately for at least 15 minutes while removing contaminated clothing. Or in the eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. While, it's inhaled: Remove from exposure and move to fresh air immediately. Then you have the ingesting of the product: Wash mouth out with water. Notes to physician: Treat supportively and symptomatically.
In addition, D(+)-Sucrose (CAS NO.57-50-1) could be stable under normal temperatures and pressures. It is not compatible with strong oxidizing agents, and you must not take it with incompatible materials. And also prevent it to broken down into hazardous decomposition products: Carbon monoxide, carbon dioxide.
