L-Histidine

Description

1. Product Overview

L-Histidine is a high-purity, essential amino acid serving as a critical biochemical building block for pharmaceutical synthesis, nutritional formulations, and advanced bioprocessing. Its primary industrial use spans cell culture media production, active pharmaceutical ingredient (API) manufacturing for metabolic therapies, and specialty supplement applications requiring precise nitrogen chelation. The key value proposition is its consistent, low-endotoxin profile enabling high-yield biomanufacturing, positioning L-Histidine as a strategic raw material for companies scaling mRNA vaccine platforms, IV nutrition, and peptide therapeutics in a supply-constrained market.

2. Key Specifications & Technical Characteristics

• Chemical Composition: C₆H₉N₃O₂ (L-α-Amino-β-imidazolepropionic acid); CAS 71-00-1

• Purity Level: ≥ 98.5% to 99.5% (FCC, USP-NF, EP grade available); heavy metals ≤ 10 ppm

• Physical Characteristics: White crystalline powder; odorless; slight saline taste; particle size (90% through 80 mesh); bulk density 0.35–0.55 g/mL

• Optical Rotation: [α]₂₀/D +12.0° to +14.0° (c=8 in 6N HCl)

• Packaging Options: 25 kg multilayer kraft paper bags with PE liner; 500 kg FIBCs; custom 1 kg to 1,000 kg vacuum-sealed foil pouches

• Shelf Life: 36 months from manufacture when stored in sealed, dry conditions (15–25°C; RH ≤ 65%)

3. Core Industrial Applications

• Pharmaceutical & API Manufacturing: Used as a chelating agent in parenteral nutrition (TPN) and as a precursor for histamine antagonists. Outperforms lower-grade amino acids due to < 0.1 EU/mg endotoxin levels, reducing pyrogenic risk in IV formulations.

• Bioprocessing & Cell Culture Media: Essential component in CHO cell and hybridoma media for monoclonal antibody and viral vector production. Its superior buffering capacity near physiological pH (pKa ~6.0) maintains viability in high-density bioreactors, increasing titers by 8–12% over alternative supplements.

• Sports Nutrition & Specialty Supplements: Incorporated into recovery blends and electrolyte matrices. L-Histidine’s natural carnosine-boosting effect reduces muscle fatigue more efficiently than beta-alanine alone, allowing lower effective dosages per unit.

• Cosmeceutical & Wound Care: Used in collagen synthesis formulations and enzymatic debriding agents. Its antioxidant metal-chelating action prevents Fenton chemistry, extending formulation stability by 30% compared to non-chelated alternatives.

4. Competitive Advantages
