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.

Histochemical staining has been shown to be useful for diagnosing autoimmune diseases such as Crohn's disease or ulcerative colitis.</p>Formula:C20H14O2S2Purity:Min. 95%Color and Shape:PowderMolecular weight:350.46 g/molIpratropium bromide monohydrate

CAS:<p>3,3'-Diindolyl is a molecule that belongs to the class of oxindoles. Oxindoles are bioactive molecules that are formed by the reduction of 3,3'-dihydroxyindole (oxindole). The borohydride reduction of 3,3'-dihydroxyindole yields 3,3'-diindolyl. It has been shown to have anti-inflammatory properties and can be used for the treatment of inflammatory diseases such as congestive heart failure. 3,3'-Diindolyl is also an acidic compound and therefore can be used as an acidic buffer in pharmacopeia. It reacts with peroxide to form an aldehyde after oxidation. This reaction is catalyzed by sodium borohydride reduction or hydrogen peroxide. The borohydride reduction of 3,3'-diindolyl yields 2-hydroxy-1-(2-hydroxyethyl) indole (oxindole).</p>Formula:C16H12N2Purity:Min. 95%Color and Shape:PowderMolecular weight:232.28 g/mol3-Fluoro-DL-tyrosine
CAS:<p>3-Fluoro-DL-tyrosine is a model system for the study of tyrosine transfer reactions. It is used to study the reaction mechanism and kinetics of tyrosine transfer from a donor molecule to an acceptor molecule. 3-Fluoro-DL-tyrosine reacts with trifluoroacetic acid to form 3,4-dihydroxybenzoic acid, which is a chemical analog of tyrosine. The hydroxyl group on this molecule can react with the proton on the amino acid side chain, forming a covalent bond that does not break down under normal conditions. This reaction is reversible and has been shown to be catalyzed by polymerase chain reactions (PCR).</p>Formula:C9H10FNO3Purity:Min. 95%Color and Shape:PowderMolecular weight:199.18 g/molRiboflavin 5'-phosphate sodium
CAS:<p>Riboflavin 5'-phosphate sodium (RB5P) is a form of riboflavin that is used as a co-substrate for the synthesis of other riboflavin-containing compounds. RB5P is an important component in biochemical research, wastewater treatment, and neurodegenerative diseases. The monosodium salt has been shown to be a useful model system for studying the biochemical properties of riboflavin. In vitro studies have shown that RB5P can be used to measure the transfer reactions between nucleotide diphosphates, such as ATP and GTP. RB5P has been used to study the structural analysis and thermodynamic data of dinucleotide phosphate.</p>Formula:C17H20N4NaO9PPurity:73.00 To 79.00%Color and Shape:Yellow Orange PowderMolecular weight:478.33 g/mol2,6-Naphthalenedicarboxylic acid
CAS:<p>2,6-Naphthalenedicarboxylic acid is a synthetic organic compound that belongs to the group of fatty acids. It is produced by oxidation of 2,6-naphthoquinone with sodium carbonate and glycol ester in the presence of an oxidation catalyst. The reaction mechanism appears to involve hydrogen bonding interactions between the hydroxyl groups on the glycol ester and the carboxyl groups on 2,6-naphthoquinone. 2,6-Naphthalenedicarboxylic acid has been shown to bind to intracellular targets such as transfer reactions and fatty acid synthesis. The analytical method for this compound is based on its formation of an adduct with p-hydroxybenzoic acid in hydrochloric acid solution.</p>Formula:C12H8O4Purity:Min. 95%Color and Shape:PowderMolecular weight:216.19 g/molβ-Naphthoic acid ethyl ester
CAS:β-Naphthoic acid ethyl ester (BNAE) is a synthetic compound that has been used as an intermediate in the synthesis of organic compounds. It is also used to prepare hydroxamic acids, which are active methylene compounds. BNAE reacts with nucleophiles and is susceptible to nucleophilic attack. The reaction mechanism for this type of compound involves a cavity with a constant volume, which increases the reactivity of the molecule. This type of reaction can be explained using the functional theory and the use of organic solvents. BNAE is stable when exposed to carbon tetrachloride and hydroxamic acids, but not when exposed to diethyl succinate or chemical agents such as sodium nitrite.Formula:C13H12O2Purity:Min. 95%Color and Shape:PowderMolecular weight:200.23 g/mol
