General description

Folic acid is mostly obtained from the diet itself or from pharmaceutical drugs such as vitamin pills.† It is highly necessary to consume folic acid for the prevention of neural tube defects, mainly anencephaly and spina bifida.† It belongs to the class of water soluble B vitamins called folates. It is mainly used to fortify cereals/grains and dietary supplements.
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.


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.
Folic acid may be used as a pharmaceutical reference standard for the quantification of the analyte in pharmaceutical formulations using ultraviolet spectrophotometric technique and microemulsion electrokinetic chromatography.

Analysis Note

These secondary standards offer multi-traceability to the USP, EP (PhEur) and BP 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.
