BPA meaning in Chemistry ?

Answer:

What is Bisphenol A mean?

Bisphenol A (BPA) is an organic synthetic compound with the chemical formula (CH3)2C(C6H4OH)2 belonging to the group of diphenylmethane derivatives and bisphenols, with two hydroxyphenyl groups. It is a colorless solid that is soluble in organic solvents, but poorly soluble in water (0.344 wt % at 83 °C).

BPA is a precursor to important plastics, primarily certain polycarbonates and epoxy resins, as well as some polysulfones and certain niche materials. BPA-based plastic is clear, tough, and flame resistant. Major areas of application include electronics (e.g., housing for electrical gear), construction materials (e.g. windows), automotive (headlight covers), data storage (e.g. CDs). In 2015, an estimated 4 million tonnes of BPA-derived chemical were produced, making it one of the highest volume organic chemicals produced worldwide.

BPA is a xenoestrogen, exhibiting estrogen-mimicking, hormone-like properties. Although the effect is very weak, the pervasiveness of BPA-containing materials raises concerns. Since 2008, several governments have investigated its safety, which prompted some retailers to withdraw polycarbonate products. Since then, BPA-free plastics have been manufactured using alternative bisphenols such as bisphenol S and bisphenol F, but there is controversy around whether these are actually safer.
