The classification of standard products not only makes many people misunderstood, but also makes many people confused between standard products and reference products, thinking that as long as the products with CAS number are standard reference products, many people are easy to confuse, in order to let more people have a new understanding of standard products, the following small series to give you a detailed definition of standard products, what is standard products.

Standard product definition:

Standard: A standard is a batch of samples having one or more chemical, physical, biological, engineering, or sensory performance characteristics that are sufficiently uniform, have been technically certified, and are accompanied by a certificate describing the relevant performance data.

Since the standard product is produced in each batch, it is sampled for analysis and determination, and then bottled; Therefore, the standard product must be uniform in nature, so that the same batch of products are consistent in the nature and value of the calibration; Only when this condition is met, the value on the certificate is meaningful to the product used by the customer; Accurate setting: A standard must be very accurate in its characteristics or values because it is used as a standard for measurement.

In nature, the standard product, that is, the standard item, is the Chinese medicine standard reference product research center agent as a measuring standard; In terms of drugs, it is the standard content in the content determination, and the standard products include stoichiometric standards, metallurgical standards and drug testing standards, so the standard products are purified from the raw material.

The above content is the definition of standard products, what is the introduction of standard products, standard products in the national drug standards for identification, inspection, content determination, impurities and related substances inspection and other standard substances, it is an integral part of the national drug standards.
