Pharmaceutical Standards
Pharmaceutical standards are a comprehensive set of reference materials essential for ensuring the safety, efficacy, and quality of pharmaceutical products. This category includes standards for active pharmaceutical ingredients (APIs), which are the core components responsible for therapeutic effects. Additionally, it covers compounds and metabolites relevant to both the pharmaceutical and veterinary industries, providing benchmarks for the accurate measurement and analysis of these substances. Nitrosamine control standards are crucial for detecting and mitigating potentially harmful nitrosamines in drug formulations. Toxicology standards help assess the safety and potential adverse effects of pharmaceutical compounds. Furthermore, enzyme activators and inhibitors standards are vital for research and development, enabling precise studies of biochemical pathways and drug mechanisms. These pharmaceutical standards are indispensable tools for regulatory compliance, quality control, and research, ensuring that pharmaceutical products meet stringent safety and effectiveness criteria.

CAS:D-Threonine is a non-essential amino acid that is used in the synthesis of proteins. It is an essential amino acid for humans, and its production can be catalyzed by aldolase enzymes. D-Threonine has been shown to have anti-inflammatory properties, which may be due to its ability to inhibit the reaction mechanism of hydroxyl group enzymes. D-Threonine also inhibits cell lysis through the inhibition of certain bacterial enzymes, such as genus or kinetic. D-Threonine can also be synthetized from L-threonine by enzyme inhibitors or asymmetric synthesis.Formula:C4H9NO3Purity:Min. 95%Color and Shape:PowderMolecular weight:119.12 g/molZ-L-tyrosine 4-nitrophenyl ester
CAS:<p>Z-L-tyrosine 4-nitrophenyl ester is a synthetic, inactivated amide that binds to the active site of enzyme, preventing its enzymatic activity. It prevents the formation of clots by cleaving the clotting factors and is used in blood transfusions. Z-L-tyrosine 4-nitrophenyl ester has been shown to inhibit the synthesis of surfactant and is used as an antiseptic. This drug can be prepared by reacting L-tyrosine with nitrophenol (NO2) in the presence of a base such as sodium hydroxide or potassium carbonate, followed by purification on sephadex g-100 columns. The product is then treated with hydrostatic pressure to remove any unreacted starting materials. This drug also has a sedimentation rate of about 1.5 x 10^6 cm/s.</p>Formula:C23H20N2O7Purity:Min. 95%Color and Shape:White/Off-White SolidMolecular weight:436.41 g/molCaffeidine
CAS:Caffeine is a stimulant that is found in coffee, tea, and some soft drinks. It can also be used to treat certain medical conditions. Caffeine is a reactive molecule that binds to human serum proteins and has been shown to have chronic oral toxicity in rats. The methylation of caffeine leads to the formation of 1-methylxanthine, which has been shown to cause cancer in animal models when given chronically. Caffeine's carcinogenic effects are due to its ability to induce DNA mutations by reacting with oxygen radicals and oxidizing DNA bases as well as inhibiting DNA repair enzymes. Caffeine's chemical diversity makes it difficult for researchers to study its carcinogenicity.Formula:C7H12N4OPurity:Min. 95%Color and Shape:White PowderMolecular weight:168.2 g/mol
