USP FAQs

Q1: can the standard confirmed in the laboratory replace USP standard?

A1: USP standard, which is explicitly mentioned in USP Pharmacopoeia and considered as a part of the statutory method. In case of any objection, the compliance shall be determined by USP individual theory and its related USP standard. The use of secondary standards is determined by the user. USP does not comment on the use of secondary standards instead of USP standards (primary standards).

Q2: how to determine whether USP standard is still valid or expired?

A2: except for USP prednisone tables RS directory 1559505, many USP standards do not have a valid date of use. As long as the batch is listed as "current batch", it is valid and usable. Once the current batch is used up, it becomes "previous batch". Specify a valid use date, usually 3-12 months from the date of use.

During the validity period, it is the user's responsibility to determine that a specific batch of USP standard has the official identity as "current batch" or "previous batch". The USP standard catalog and USP online store are updated daily. USP recommends that at least one of these sources be referred to before using USP standards to ensure that the batch can be used effectively.
