In Chemical Terms, Resorcinol Has The Formula C6H6O2

 

Resorcinol 

Resorcinol is a phenol that has had a hydroxyl in the meta position replaced. Pyrocatechol is a phenol substituted by an orthohydroxyl group, while hydroquinone is a phenol substituted by a parahydroxyl group. m-dihydroxybenzene, 1,3-dihydroxybenzene, and benzenediol-1,3 are other names for resorcinol. It is a crystalline powder that is soluble and dissolves at 111°C and 281°C, respectively. Resorcinol, like phenol, is a protoplasmic toxin that kills cells by inactivating enzymes, denaturing proteins, and creating insoluble proteins. In addition, both phenol and resorcinol affect the cellular membrane, altering its physical characteristics to vary its selective permeability. Cell death is the result of this alteration in permeability.

According To Coherent Market Insights, The Global Resorcinol Market Size Is Estimated To Reach US$ 570 Million By 2027, And Register A CAGR Of 3.1% Over The Forecast Period (2019 - 2027).

Phenol is a more potent toxin when used alone, and it also has a secondary anaesthetic effect since it inhibits sensory nerve endings.  At 80% concentration, phenol and (to a lesser extent) Resorcinol are excreted from the body either unaltered or conjugated with glucuronic or sulfuric acid. They are cardiac, renal, and hepatic poisons.

Resorcinol is a phenolic chemical that is included in many items, including roasted barley, canned molasses, adhesives, hair dyes, and cosmetics. It is employed in many industrial processes, including tanning, tyre manufacture, and photography. Higher concentrations of resorcinol are caused by coal and shale deposits in drinking water. It is believed that resorcinol inhibits TPO activity. Animal studies show an inconsistent effect of resorcinol on thyroid weight and function, as evaluated by Lynch et al. (2002). Resorcinol has been shown in some trials to have goitrogenic effects, but only when exposed to levels that are consistently high, such as by daily oral exposure, subcutaneous oil delivery (but not aqueous solutions), or extremely high doses applied topically twice daily.

Studies on people who were exposed to Resorcinol at work have not revealed any effects on thyroid function. Data indicating greater resorcinol levels in drinking water in areas with a high prevalence of goitre as compared to surrounding areas with a lower prevalence of goitre but equivalent urinary iodine levels provide epidemiologic support for the goitrogenic action of resorcinol in humans. Any conclusive findings, however, are precluded by a number of further variations in the study communities and their water sources.

There are numerous case reports of hypothyroidism and/or goitre caused by extremely high doses (> 30 mg/kg/day) of topical resorcinol-containing drugs administered over a prolonged period of time to large regions of the body, particularly when applied to areas with open sores or ulceration. In these cases, stopping resorcinol led to the disappearance of goitre and hypothyroidism. It is encouraging to know that applying Resorcinol -containing drugs at a regular dose to healthy skin does not seem to affect thyroid function.

Butadiene- The organic molecule Butadiene has the formula (CH2=CH)2. It is an easily condensable colourless gas that becomes a liquid. Industrially speaking, it is significant as a forerunner to synthetic rubber. You can think of the molecule as the union of two vinyl groups. The simplest conjugated diene is this one. Although butadiene degrades quickly in the environment, it is nevertheless present in the ambient air in urban and suburban regions due to frequent automobile emissions. The isomer Butadiene, a cumulated diene with the structure H2C=C=CHCH3, is also known by the name butadiene. There is no industrial use for this allene.
