Descrição

Descrição geral

Malic acid is a naturally occurring acidulant and low acid food additive, present in most fruits and vegetables. It is widely used to enhance the flavor, adjust the pH value of alkaline products and to control the growth of bacteria.

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.

Aplicação

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.

Nota de análise

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