| Pesticides | Synthesis of biologically active cyclohexene-based insecticides or plant growth regulators | Used as a chiral building block in functional group transformations of cyclohexene derivatives to generate stereoselective active ingredients |
| Chemical Reagents | Chiral catalysis research and asymmetric reaction templates in laboratory settings | Employed as a chiral ligand or auxiliary in transition metal-catalyzed asymmetric addition, hydrogenation, or cyclization reactions |
Manufacturing Quality Control of (S)-(-)-3-CYCLOHEXENECARBOXYLIC ACID
| Test Item | Common Testing Method | Method Overview |
|---|---|---|
| Appearance and Physical Form | Visual Inspection + Physical Property Determination | Observe sample color and state (typically a colorless to pale yellow liquid or low-melting solid), and determine melting or boiling point range, conforming to pharmacopoeial or enterprise standards. |
| Purity (Assay) | High-Performance Liquid Chromatography (HPLC) | Use a C18 column with water-acetonitrile or methanol as mobile phase, and a UV detector (210–254 nm) to quantify the main component via external or internal standard method. Purity typically required to be ≥98.0%. |
| Enantiomeric Purity (ee Value) | Chiral High-Performance Liquid Chromatography (Chiral HPLC) | Employ chiral stationary phase columns (e.g., Chiralpak AD-H, OD-H, or similar) to separate (S)- and (R)-enantiomers. Enantiomeric excess (ee) is calculated from peak areas, typically requiring ≥99% ee. |
| Moisture Content | Karl Fischer Titration | Quantify trace water content using the reaction of iodine, sulfur dioxide, pyridine, and methanol. Suitable for organic acid compounds, with moisture controlled ≤0.5%. |
| Residual Solvents | Gas Chromatography (GC) | Using headspace or direct injection, with a capillary column (e.g., DB-624) and FID detector, to detect residual solvents such as ethanol, acetone, ethyl acetate, etc., in compliance with ICH Q3C guidelines. |
| Heavy Metal Content | Atomic Absorption Spectroscopy (AAS) or ICP-MS | After sample digestion, determine levels of heavy metals such as lead, cadmium, mercury, and arsenic, meeting pharmacopoeial limits (e.g., Pb ≤5 ppm). |
| Acid Value (Total Acid Content) | Alkaline Titration | Titrate the sample with standard sodium hydroxide solution using phenolphthalein as indicator. Acid value (mg KOH/g) is calculated to verify carboxyl group content against theoretical value. |
| UV Absorption Characteristics | UV-Visible Spectrophotometry (UV-Vis) | Measure maximum absorption wavelength (λmax, typically around 210–220 nm) within the 200–300 nm range, used for preliminary identification and purity screening. |
| Melting Point / Boiling Point | Melting Point Apparatus / Boiling Point Determination | Determine physical constants; (S)-(-)-3-Cyclohexenecarboxylic acid has a melting point of approximately 20–25°C (liquid) and boiling point of about 180–190°C (at atmospheric pressure), used for auxiliary identification. |
| Impurities (e.g., Chlorides, Sulfates) | Ion Chromatography (IC) or Colorimetric Methods | Use ion chromatography to detect anionic impurities (Cl⁻, SO₄²⁻), or classical colorimetric methods (e.g., silver chloride precipitation) to control inorganic impurity levels. |
| Microbial Limits (if applicable) | Microbial Limit Test (Pharmacopoeial Method) | If used as a pharmaceutical intermediate or active pharmaceutical ingredient, test for total aerobic microbial count, molds and yeasts, and specified pathogens (e.g., Escherichia coli), meeting USP/EP microbial limits. |
