About Lactose

Vaqora Chemicals supplies Lactose, a high-purity reference standard of Lactose registered under CAS number 14641-93-1. Formula C12H22O11, molecular weight 342.3 g/mol. Common synonyms include Lactose (100 mesh) and Lactose (200 mesh).

It is supplied as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. Handle it with standard laboratory precautions and appropriate personal protective equipment.

As a reference sample of Lactose, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

Standard pack sizes are 10 mg, 25 mg, 50 mg and 100 mg, and every batch ships with a Certificate of Analysis (COA) and we export worldwide.
