Ammonium hydroxide nh 4 oh

Manufactured by Sinopharm

Sourced in China

Ammonium hydroxide (NH4OH) is a clear, colorless aqueous solution that is widely used in various industrial and laboratory applications. It is a weak base that dissociates in water to form ammonium ions (NH4+) and hydroxide ions (OH-). Ammonium hydroxide is a common reagent used in analytical chemistry, pH adjustment, and as a cleaning agent.

High-purity (>97 %) standard solutions of the target compounds (METH, AMP, MDMA, MDA, KET, NK, COC, BE, Mor, Cod, MTD, EDDP, and 6-AM) and their deuterated analogues (METH-d8, AMP-d8, MDMA-d5, MDA-d5, KET-d4, NK-d4, COC-d3, BE-d3, Mor-d3, Cod-d6, MTD-d9, EDDP-d3, and 6-AM-d6) used as internal standards (purity >98 %) were purchased from Cerilliant (Round Rock, TX, USA). Individual stock solutions were prepared by diluting each analyte solution with acetonitrile (AcN) (HPLC grade, Fisher Science). Working standard mixtures were prepared at different concentrations by the appropriate dilution of the individual stock solutions with AcN. All of the stock and working standard solutions were stored in the dark at -20 °C. Highpurity water was prepared with a Milli-Q system (Millipore, MA, USA). Oasis MCX (60 mg, 3 mL) solid-phase extraction (SPE) cartridges were purchased from Waters Corporation (Milford, MA, USA). A CNW™ SPE vacuum manifold (CNW Technologies GmbH) was used for the SPE clean-up processes. Ammonium hydroxide (NH 4 OH) was purchased from Sinopharm Chemical Regent Co. Ltd. (Beijing, China). Ammonium acetate (HPLC grade) was obtained from CNW Technologies GmbH (Düsseldorf, Germany).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
