It can be stored in Fridge for a week. Question: How do you add this
diazomethane hexane (let's say 4ml) to the sample? Is it safe to use glass
pipette to transfer? Thanks in advanced. |

explosive compound. It could explode anytime. |

Since I always added excess, I directly added it with appropriate volume,
before I was told do not used needles. You can use graduate cylinder. |

diazomethane, it is not explosive. Treat TMS-diazomethane with utmost care
