Vitamin U, despite its name, is not a true vitamin but a sulfur-containing organosulfur compound identified in cabbage juice by Garnett Cheney in 1950. The most common form, S-methylmethionine sulfonium chloride (SMMS), is a white crystalline powder with a molecular formula of C6H14ClNO2S and a molecular weight of 191.67 g/mol. Highly soluble in water (50 g/100 mL at 25°C), it features a sulfonium group, making it a source of labile methyl groups for biochemical reactions. Stable under normal conditions, it is heat-resistant up to 120°C, suitable for food processing. <table> <tbody> <tr> <td width="308">Product Name</td> <td width="401">Vitamin U</td> </tr> <tr> <td width="308">Appearance</td> <td width="401">White Powder</td> </tr> <tr> <td width="308">Specification</td> <td width="401">98%</td> </tr> <tr> <td width="308">Test Method</td> <td width="401">HPLC</td> </tr> <tr> <td width="308">CAS No</td> <td width="401">3493-12-7</td> </tr> <tr> <td width="308">MF</td> <td width="401">C6H14ClNO2S</td> </tr> <tr> <td width="308">Certificate</td> <td width="401">ISO/cGMP/KOSHER/HALAL/USDA ORGANIC</td> </tr> </tbody> </table>
