Analysis Note

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

Application

Sulfamerazine may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using spectrophototmetric technique.
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.

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. Sulfamerazine belongs to the class of sulfonamides, used as an antibacterial agent to treat infections, especially for patients intolerant to antibiotics.

A rapid, selective and simple spectrophotometric method for the determination of sulfa-drugs is described. The method is based on the formation of violet colored azo product by the diazotization of sulfonamides, viz. sulfathiazole (SFT), sulfadiazine (SFD), sulfacetamide (SFA), sulfamethoxazole (SFMx)
