L-Ascorbic Acid (Standard) is a high-purity analytical reference standard (99.97%) used in chromatographic and analytical research applications including HPLC, GC, and mass spectrometry (MS). Also known as Vitamin C or L-ascorbate, this compound is a naturally occurring water-soluble antioxidant widely distributed in plants and biological systems.
L-Ascorbic acid functions as an electron donor and endogenous antioxidant, playing a crucial role in neutralizing reactive oxygen species (ROS) and protecting cells from oxidative stress. In biochemical and pharmacological studies, L-ascorbic acid has been shown to selectively inhibit Cav3.2 calcium channels (IC₅₀ ≈ 6.5 μM) and to influence cellular processes such as collagen deposition and elastogenesis.
Because of its well-characterized chemical and biological properties, this compound is widely used as a reference standard for analytical calibration, method development, and validation in pharmaceutical, nutraceutical, food chemistry, and metabolomics research.
