General description

Pharmaceutical secondary standards for application in quality control, provide pharma laboratories and manufacturers with a convenient and cost-effective alternative to the preparation of in-house working standards.
Promethazine hydrochloride belongs to the group of phenothiazine derivatives. It is commonly used as an antihistaminic for most prominently enhancing the anesthetic, sedative and analgesic effect of other drugs. It also shows antipyretic and antiemetic properties, when used in combination with paracetamol. It is also used to provide symptomatic relief of hypersensitivity reactions.

Application

These Secondary Standards are qualified as Certified Reference Materials. These are suitable for use in several analytical applications including but not limited to pharma release testing, pharma method development for qualitative and quantitative analyses, food and beverage quality control testing, and other calibration requirements.
Promethazine hydrochloride may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using spectroanalytical technique.

Analysis Note

These secondary standards offer multi-traceability to the USP and EP primary standards, where they are available.

Other Notes

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.
