This character is a Math Symbol and is commonly used, that is, in no specific script.
The glyph is not a composition. It has no designated width in East Asian texts. In bidirectional text it acts as Other Neutral. When changing direction it is mirrored into Righthand Interior Product. The word that U+2A3C forms with similar adjacent characters prevents a line break inside it.
The CLDR project calls this character “interior product” for use in screen reading software. It assigns these additional labels, e.g. for search in emoji pickers: interior, product.
The Wikipedia has the following information about this codepoint:
In mathematics, the interior product (also known as interior derivative, interior multiplication, inner multiplication, inner derivative, insertion operator, or inner derivation) is a degree −1 (anti)derivation on the exterior algebra of differential forms on a smooth manifold. The interior product, named in opposition to the exterior product, should not be confused with an inner product. The interior product is sometimes written as
