Precision casting wax is widely used in the manufacture of metal parts that require high precision and complex structures, typical areas include: Aerospace: high-temperature alloy parts such as turbine blades and engine components. Medical devices: casting of surgical instruments, orthopedic implants (such as titanium alloy joints). Jewelry: production of fine patterned precious metal (gold, silver) jewelry. Automotive industry: precision gears, sensor components, exhaust system parts. Industrial machinery: pumps and valves, hydraulic parts, rapid prototyping of complex molds. Art casting: sculpture, handicrafts and other metal artwork with high detail requirements. Advantages of Precision Casting Wax High dimensional stability: very low shrinkage under temperature and humidity changes, maintains the precise shape of the mold and is suitable for manufacturing complex, high-precision parts. Excellent fluidity: after melting, it can fully fill the details of the mold and replicate fine patterns (e.g. turbine blades, jewelry patterns, etc.). Low ash residue: minimal ash residue after burning or dewaxing to avoid casting surface defects. Easy mold release: low adhesion to shell materials (e.g. ceramic shells), quick and complete melting out of the wax during dewaxing, reducing the risk of shell breakage. Reusability: Waste wax can be recycled and reused, reducing costs. Environmental protection and safety: Modern investment casting waxes are mostly formulated with non-toxic, low volatility synthetic waxes or natural waxes, which are in line with environmental standards.

The introduction of the oral phosphodiesterase type 5 (PDE5) inhibitor sildenafil citrate (trade name: Viagra) opened a new chapter in the history of erectile dysfunction (ED) treatment. Since Sildenafil citrate was approved by the US Food and Drug Administration (FDA) in March 1998, the research on PDE5 inhibitors represented by Sildenafil citrate has made great progress. With the expiration of sildenafil's original research patent, it is the goal of synthesis workers to prepare high purity sildenafil citrate stably and efficiently and suitable for industrial production.

Tadalafil (market name “Cialis” or “Adcirca”) was developed by American pharmaceutical company Lilly. It is a kind of PDE5 inhibitor used for the treatment of erectile dysfunction, benign prostatic hypertrophy and pulmonary arterial hypertension.The effect of Tadalafil is relaxing the blood vessels muscles and increasing the blood flow into the corpus cavernosum. Studies show that Cialis works very quickly, taking effect in around 15-20 minutes, and has a prolonged effect that can last for up to 36 hours. T1/2 is 17.5h. Tadalafil is one of the two new PDE5 inhibitors launched for the oral treatment of male erectile dysfunction. Tadalafil is a b-carboline derivative and it is structurally distinct from vardenafil (Levitraw) and sildenafil (Viagraw), both of which are PDE5 inhibitors based on a fused pyrimidine core structure.

Phenacetin, a widely used analgesic and antipyretic drug, was first synthesized in 1878 by Harmon Northrop Morse. Derived from p-phenetidine, phenacetin's structure was confirmed through chemical analysis and testing. By 1887, it was introduced into the market by Bayer and quickly became popular due to its effectiveness in reducing pain and fever. Its chemical composition and pharmacological properties have made it a significant compound in medicinal chemistry. Phenacetin was primarily used to treat mild to moderate pain, such as headaches, toothaches, and menstrual cramps. Its antipyretic properties also made it effective in reducing fever. For many years, it was a common ingredient in over-the-counter pain relief medications and was often combined with other analgesics like aspirin or caffeine to enhance its effects. Phenacetin was frequently used in combination drugs, such as APC (aspirin, phenacetin, and caffeine) tablets, which were popular for treating pain and inflammation. These combinations provided synergistic effects, improving the overall efficacy of pain relief medications.
