Application Features: High-purity intermediate (98.5%) with highly reactive carbonyl group; readily reduced to alcohol or converted to amine. Key raw material for toperisone hydrochloride synthesis; inter-batch impurity variation <0.3%.

Application Features: Bifunctional intermediate: hydroxyl group enables esterification/etherification; chlorine supports metal-catalyzed cross-coupling. Extensively used in fenofibric acid synthesis.

Application Features: Highly reactive electrophile; readily undergoes reactions with Grignard reagents or cyanides. Key intermediate in synthesizing pyrethroid insecticides (e.g., cypermethrin).

Application Features: Classic fragrance compound (98% purity) with fresh almond-cherry notes; widely used in toothpaste and oral care formulations. Also serves as a key intermediate for celecoxib (pharmaceutical) and cyazofamid (fungicide).

Application Features: High-purity intermediate (≥99%); para-ethyl group enhances lipophilicity, promoting drug absorption and distribution. Critical precursor for specific cardiovascular agents and chiral active pharmaceutical ingredients.

Application Features: Key pharmaceutical intermediate featuring reactive phenolic hydroxyl and ketone carbonyl groups; commonly employed in synthesizing β-blockers, bronchodilators, and related therapeutics.

Application Features: Key intermediate in pharmaceutical and organic synthesis; unique para-chloro-substituted propiophenone structure serves as a core building block for diverse drug molecules.

Application Features: Strong electron-withdrawing fluorine atom enhances intermediate stability; essential building block for fluoroquinolone antibiotics (e.g., ciprofloxacin); 99% purity ensures high-efficiency fluorination.

Application Features: Ortho-methyl group restricts intramolecular rotation, enhancing spatial selectivity in derivatives; used to synthesize chiral agrochemicals (e.g., pyrethroids) with controllable stereoisomer ratios.

Application Features: Ortho-methyl effect promotes cyclization; key building block for fragrances (e.g., jasmone) and antifungal agents; 99% purity reduces isomeric byproducts.

Application Features: Biphenyl structure extends conjugation, serving as a critical backbone for anti-tumor agents (e.g., paclitaxel side chains) and liquid crystal materials.

Application Features: Dimethoxy groups protect phenolic hydroxyl functionality, enabling multi-step synthesis pathways (e.g., benzene ring modification in opioid drug synthesis).
