1. Product Overview & Specifications

Parameter Specification Competitor A Competitor B
Molecular Formula C8H8ClNO2 C7H6ClNO C8H7ClO2
Purity ≥99.2% 98.5% 97.8%
Melting Point 112-114°C 105-108°C 98-102°C
Storage 2-8°C (desiccated) Ambient 0-5°C

Notable features: Enhanced thermal stability (+15% vs. alternatives) and reduced hygroscopicity for superior handling in organic synthesis.

2. Key Applications & Industrial Uses

Pharmaceutical Intermediates

Critical precursor in synthesizing kinase inhibitors (e.g., EGFR inhibitors) with 23% higher yield compared to traditional pyridine derivatives.

Agrochemical Production

Essential component in next-gen fungicides, demonstrating 40% improved systemic mobility in plant vascular systems.

Coordination Chemistry

Effective ligand for transition metal catalysts in asymmetric hydrogenation reactions (up to 92% ee achieved).

3. Operational Guidelines & Best Practices

Handling Protocol

1. Always use nitrogen-purged environments for moisture-sensitive reactions
2. Optimal solubility: 18 mg/mL in DCM at 25°C
3. Incompatible with strong reducing agents (e.g., LiAlH4)

Synthetic Example

Antifungal Agent Synthesis:
Step 1: React with thiophosgene (1:1.2 molar ratio) at -15°C
Step 2: Couple with triazole derivative (Pd(OAc)2 catalyst)
Final yield: 78-82% (HPLC purity >99%)
