Resorcinol (Hydroquinone), with the chemical formula C6H4(OH)2, is primarily used in various industries such as pharmaceuticals, cosmetics, electronics, and photography. As a phenolic compound, it is mainly used in dermatological treatments, particularly effective in addressing hyperpigmentation issues. Pharmaceutical grade resorcinol is commonly a key ingredient in whitening and spot-removal products, playing a role in treating skin problems like hyperpigmentation, freckles, and age spots.

Due to its certain toxicity, the quality standards and safety requirements for resorcinol are particularly important. To ensure its safety and efficacy in pharmaceuticals, the quality standards and uses of pharmaceutical grade resorcinol are strictly regulated.

II. Chinese Pharmacopoeia Quality Standards for Pharmaceutical Grade Resorcinol

According to the Chinese Pharmacopoeia, the quality standards for pharmaceutical grade resorcinol include its appearance, identification, assay, impurity control, solubility, microbial limits, etc. Specific requirements are as follows:

1. Appearance and Properties

- Pharmaceutical grade resorcinol should be a white or off-white crystalline powder, odorless or almost odorless. It should remain stable under dry conditions and be free of visible impurities. Its appearance must meet pharmacopoeial standards to ensure purity and quality.

2. Identification

- Identification of resorcinol can be performed using ultraviolet spectrophotometry, typically by measuring the absorbance at specific wavelengths to confirm compliance with standards. Additionally, high-performance liquid chromatography (HPLC) can be used for qualitative analysis to ensure component purity.

3. Assay

- The assay of resorcinol is usually conducted using high-performance liquid chromatography (HPLC), calculating the content by comparing the chromatographic peak areas of the sample and standard solutions.

- According to the Chinese Pharmacopoeia, the content of pharmaceutical grade resorcinol should be between 98% and 102% to ensure the active ingredient delivers the intended therapeutic effect.
