Description
SODIUM FORMATE SALT
Mono • Di • Tri • Anhydrous | IP • BP • USP • LR • AR Grades
Sodium Formate is the sodium salt of formic acid, available in four forms — Monosodium Formate, Disodium Formate, Trisodium Formate, and Anhydrous. It is a white, odourless to faint formic acid odour, crystalline powder or granules that is freely soluble in water and exhibits a mildly alkaline pH in solution. Aaru Life Science supplies Sodium Formate in multiple pharmacopoeial and laboratory grades including IP, BP, USP, LR, and AR, ensuring suitability across a wide range of pharmaceutical, food, analytical, and industrial applications. Each batch is manufactured under strict quality control and is compliant with the respective pharmacopoeial standards, making it a reliable choice for formulators, researchers, and industrial users alike.
