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

Dear DCHAS Listers:

å

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.

å å å

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

å

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

å

When a flask can be labeled during routine lab work?å 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.

å

Regards,

Tilak
