 a HPLC Method for Paclobutrazol, Uniconazole-P, Fipronil, Daminozide on Newcrom R1 by SIELC Technologies

 

 

High Performance Liquid Chromatography (HPLC) Method for Analysis of Paclobutrazol, Uniconazole-P, Fipronil, Daminozide.

Daminozide is a plant growth regulator with the chemical formula C6H12N2O3. It has a variety of alternate names including: aminozide, Alar, Kylar, SADH, B-995, B-nine, and DMASA. As a pesticide, works through inhibiting the production of gibberellins. It was typically used in trees that produced fruit for consumption, but was withdrawn due to concerns of it being a carcinogen. It is still occasionally used in ornamental plants.

Paclobutrazol (PBZ) is an organic fungicide with the chemical formula C15H20ClN3O. It works through inhibiting the production of gibberellins, which are plant growth hormones. Through reducing reducing internodal growth, it causes stronger stems, greater root growth, and earlier fruitset. It can also reduce frost sensitivity in plants.

Uniconazole is a plant growth regulator with the chemical formula C15H18ClN3O. As a pesticide, works through inhibiting the production of gibberellins, which are plant growth hormones. It is typically used in perennials and ornamental plants to ensure they are a marketable size before they bloom.

Fipronil is an insecticide with the chemical formula C12H4Cl2F6N4OS. It works through causing hyperexcitation of the nerves and muscles in contaminated insects.  In Texas, it is often used to control invasive species of ants and wasps. It is also an active ingredient in flea and tick treatments for pets. WHO classifies it as a Class II, moderately hazardous, pesticide.

Paclobutrazol, Uniconazole-P, Fipronil, Daminozide can be retained and analyzed using the Newcrom R1 stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) without a buffer. Detection is performed using UV.

Separation of Paclobutrazol on Newcrom R1 HPLC column

February 16, 2018
Separation of Paclobutrazol on Newcrom C18 HPLC column

Paclobutrazol can be analyzed by this reverse phase (RP) HPLC method with simple conditions. The mobile phase contains an acetonitrile (MeCN), water, and phosphoric acid. For Mass-Spec (MS) compatible applications the phosphoric acid needs to be replaced with formic acid. Smaller 3 µm particles columns available for fast UPLC applications. This liquid chromatography method is scalable and can be used for isolation impurities in preparative separation. It also suitable for pharmacokinetics.

Application Column

Newcrom R1

The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.
