General description

Sodium dodecylbenzenesulfonate, commonly known as sodium lauryl phenyl sulfonate, is a linear alkylbenzene sulfonate that belongs to the class of anionic surfactants. Generally, it is used as an emulsifier, detergent, solubilizer and wetting agent in pharmaceutical, personal care, home care and food products.
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.

Application

Sodium dodecylbenzenesulfonate may be used as a pharmaceutical reference standard for the determination of the analyte in raw material, environmental samples, personal care and home care formulations by high performance liquid chromatography.
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.

Analysis Note

These secondary standards offer multi-traceability to the US 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.
