According to several scientific studies, the distinct UV absorption maximums for vitamin D are typically observed in the 264–266 nm range. This property is fundamental to the analytical techniques used to quantify vitamin D levels in various samples, from food products to clinical specimens.

Vitamin D, often called the “sunshine vitamin,” is essential for human health, with research showing that cutaneous synthesis provides the majority of the body's needs for most people. This vital process is triggered by a very specific and narrow frequency of light: ultraviolet B (UVB) radiation.

The common food coloring Red 40, also known as Allura Red AC, exhibits its maximum absorbance in the green-blue region of the visible light spectrum. This characteristic property is critical for both its use in food manufacturing and its analysis in a laboratory through techniques like spectrophotometry.
