Lists of "New USP Reference Standards" and "Unavailable First-time Official USP Reference Standards" are provided below. Initial qualification and requalification. Heterogeneous substances, of natural origin, also are designated Reference Standards where needed. Another reason to limit impurities is demonstrated in the following scenario. Tier 3: At least two storage conditions should be chosen: the intended storage condition and an alternative storage condition as a contingency. In addition, this type of standard reduces the degree of systematic and random error from the combined analytical tests. These tests and procedures often require the use of official USP physical reference standards. Product code: {{entry.product.displayPartCode ?
