Specification:

?Caffeic acid , its cas register number is 331-39-5. It also can be called 3,4-Dihydroxycinnamic acid ; 3,4-Dihydroxybenzeneacrylic acid ; and 3-(3,4-Dihydroxy phenyl)-2-propenoic acid .?It is a naturally occurring organic compound, and?is found in all plants because it is a key intermediate in the biosynthesis of lignin. It is hazardous, so the first aid measures and others should be known. Such as: When on the skin: first, should flush skin with plenty of water immediately for at least 15 minutes while removing contaminated clothing. Secondly, get medical aid. Or in the eyes: Flush eyes with plenty of water for at least 15 minutes, occasionally lifting the upper and lower eyelids. Then get medical aid soon.
