Where can I buy a sodium methoxide standard solution?
Thread Content
Due to the strict requirements for preparing sodium methoxide solutions – such as the absence of carbon dioxide and avoidance of contact with air – it is difficult to meet these conditions during actual preparation, which in turn makes it hard to ensure the accuracy of the calibration of such solutions. Therefore, does anyone know which domestic reagent company sells or produces standard sodium methoxide solutions?
