An anthocyanidin aglycone occurring widely in berries, grapes and other pigmented plant tissues, Petunidin chloride is the flavylium chloride that analytical laboratories treat as a phytochemical reference substance rather than as a drug-related impurity. Because anthocyanins are unstable and readily interconvert with their quinoidal and chalcone forms, a characterised single-component standard is essential for identification work in natural-product and food chemistry. Typical applications include LC-MS and HPLC method development for anthocyanin profiling, qualitative confirmation of petunidin-derived peaks in berry and wine extracts, and calibration of assays that quantify total anthocyanidin content. The material is a dark purple powder, with a molecular formula of C16H13O7·Cl and a molecular weight of 317.27 for the cation. Storage at -20°C ± 5°C is recommended, and shipments are arranged with ice packs. Pack sizes listed include 1 mg, 5 mg, 10 mg, 20 mg, 50 mg and 100 mg. Request a quotation or the supporting documentation to confirm suitability for a specific analytical method.
