IDENTIFICATION
• A. Infrared Absorption <197K>
• B. Ultraviolet Absorption <197U>
Sample solution: 8 µg/mL in methanol
Acceptance criteria: Meets the requirements
ASSAY
• Procedure
Standard solution: 8 µg/mL of USP Vanillin RS in methanol
Sample solution: 8 µg/mL of Vanillin in methanol
Blank: Methanol
Instrumental conditions
(See Spectrophotometry and Light-Scattering <851>.)
Mode: UV
Analytical wavelength: 308 nm
Cell: 1 cm
Analysis
Samples: Standard solution, Sample solution, and Blank
Calculate the percentage of vanillin (C8H8O3) in the portion of Vanillin taken:
Result = (AU/AS) × (CS/CU) × 100
AU = absorbance of the Sample solution
AS = absorbance of the Standard solution
CS = concentration of USP Vanillin RS in the Standard solution (µg/mL)
CU = concentration of the Sample solution (µg/mL)
Acceptance criteria: 97.0%~103.0% on the dried basis
IMPURITIES
• Residue on Ignition <281>: NMT 0.05%
SPECIFIC TESTS
• Melting Range or Temperature <741>: 81~83
• Loss on Drying <731>: Dry the sample over silica gel for 4 h: it loses NMT 1.0% of its weight.
ADDITIONAL REQUIREMENTS
• Packaging and Storage: Preserve in tight, light-resistant containers.
• USP Reference Standards <11>
