What is D-Tartaric acid CAS 147-71-7?
D-tartaric acid (147-71-7), as a natural dextrorotatory organic acid, its core value lies in:
Versatility: From food acidification to electronic materials, relying on its strong acidity and complexing ability;
Irreplaceable in medicine: Highly efficient chiral disintegrators, promoting the advancement of drug purification technology;
Safety first: Strict protective measures must be taken during operation to avoid inhaling dust or skin contact.
D-Tartaric acid CAS 147-71-7 Use
Food industry: Acidifiers (for beverages and jams), leavening agents (for beer foaming), regulating acidity and extending shelf life
Pharmaceutical industry: Drug dispersants, laxatives (potassium sodium tartrate), diuretics, chiral separation, regulating fluid balance
Chemical Engineering and Materials: Dye mordants (used in combination with tannin), metal polishes, epoxy resin curing accelerators, enhancing color fastness, and removing metal oxides
Electronics industry: Piezoelectric crystal materials (sensors, filters), utilizing the piezoelectric response of crystals
Environmental protection and scientific research: Adsorbents for wastewater treatment, chromatographic analysis reagents, chelating heavy metal ions
