Hi Tilak - If this lab is under the Lab Standard, there is an interpretation letter for that question.

Dear DCHAS Listers:

I am looking guidelines on ??labeling?? synthesized products/compounds in small quantities in vials/flasks (RBF). This is mainly problem in synthetic groups in the chemistry dept. Generally, synthetic chemists generate hundreds of compounds during their Ph. D. program and they like to keep a small portion of the compound for the future use such as TLC and other analytical reference purpoHi se.

What is the appropriate practice for labeling these sample vials and small flasks?

Actual chemical names/structures/Note book reference such as AB-12-B?

When a flask can be labeled during routine lab work? As an example, I am working on a column purification, and I have multiple concentrated fractions from the column.

Any information will be highly helpful.
