Product Overview & Quality

Product Name: L-Histidine monohydrochloride (L-Histidine hydrochloride monohydrate)
Brand: Kemaus (Product Code: KA-1091)
Grade: Laboratory Grade (Lab Grade) featuring a high purity of 98.5 percent or higher. Manufactured under Kemaus standard laboratory quality control to guarantee absolute physical uniformity and low trace contaminants. Excellently suited for cell culture formulations, molecular biology applications, and general biochemical laboratory assays.
Physical Properties: Odorless, white crystalline powder or white crystals with a mildly bitter taste.
Solubility: Highly soluble in water (exhibits much better solubility than the free base form of L-histidine). Yields a mildly acidic aqueous solution; practically insoluble in ether.
Key Use: Widely utilized as an essential nutrient and additive in formulating microbial culture media, tissue preparations, and specialized cell culture applications. Commonly used as a biological reagent for preparing standard buffer solutions in biochemical research, specifically effective within the pH 5.5 to 7.5 stabilization window. Also functions as a dependable reference standard in amino acid profile testing and protein structure investigations.

Safety & Hazards

Classification: Not classified as a hazardous substance according to GHS regulations. It possesses an excellent, safe, and biocompatible profile. Acts as a mild temporary physical and mechanical dust irritant.
Health Risks: Direct eye contact with large quantities of fine powder triggers minor mechanical irritation, watering, or temporary redness. Inhalation of airborne particles may induce coughing or sneezing. It is non-hazardous and benign to intact skin tissues.
First Aid Measures: Flush eyes immediately with plenty of flowing water for at least 15 minutes. Wash skin thoroughly with soap and water. Seek medical advice if irritation develops or persists.

Handling & Storage

Storage: Moisture and Light Sensitive. It can absorb ambient water vapor from damp air and is sensitive to extended light exposure. Must be stored in its original, tightly sealed Kemaus container. Keep in a cool, strictly dry, and well-ventilated dedicated space at stable room temperature (below 30 degrees Celsius). Protect from direct sunlight and high humidity to prevent severe chemical caking.
Precautions: Wear standard personal protective equipment (PPE), including laboratory gloves, safety glasses, and a particulate dust mask. Ensure the container cap is secured tightly immediately after each use to protect the purity of the chemical.
