High Purity 2-[1-(Mercaptomethyl)cyclopropyl]acetic Acid (CAS 162515-68-6) for Montelukast

2-[1-(Mercaptomethyl)cyclopropyl]acetic Acid: A Key Pharmaceutical Intermediate


2-[1-(Mercaptomethyl)cyclopropyl]acetic Acid, identified by CAS No. 162515-68-6, stands as a critical chemical intermediate in the pharmaceutical industry. This compound, also known by synonyms such as 1-(Mercaptomethyl)cyclopropaneacetic Acid, plays an indispensable role in the synthesis of Montelukast, a widely recognized medication for the treatment of asthma and allergies. Its unique molecular structure and specific chemical properties make it highly valuable in complex organic syntheses, particularly within the pharmaceutical sector where purity and consistency are paramount.


Our commitment to excellence ensures that our 2-[1-(Mercaptomethyl)cyclopropyl]acetic Acid meets stringent quality standards. It possesses a molecular formula of C6H10O2S and a molecular weight of 146.21. Physically, it typically presents as a white to off-white crystalline solid. Key physical and chemical properties include a melting point ranging from 42-45°C, a boiling point of approximately 290.1±13.0 °C at 760 mmHg, and a density of 1.2±0.1 g/cm³. The flash point is noted at 110 °C, and its refractive index is 1.538. These characteristics are consistently verified to ensure the product's suitability for high-demand applications.


Quality assurance is at the core of our production process. Each batch of 2-[1-(Mercaptomethyl)cyclopropyl]acetic Acid undergoes rigorous testing to confirm its adherence to superior specifications. We guarantee a purity level of 98.0% minimum, with typical batches exceeding 99% purity as confirmed by Gas Chromatography (GC). Advanced analytical techniques, including GC for identification and chromatographic purity, HPLC for trace impurities like thioacetic acid, and ICP for lithium content, are routinely employed. Furthermore, residual solvents such as triethylamine, dichloromethane, N,N-dimethyl formamide, toluene, and n-heptane are meticulously controlled to levels well below industry limits. Loss on drying is maintained at ≤0.5%, affirming the product’s exceptional quality and stability. Our products are carefully packed in 25kg cardboard drums or tailored to customer-specified requirements, ensuring integrity during transit and storage. We recommend storage in a cool, dry, and well-closed container, protected under an inert gas atmosphere and away from moisture and strong light/heat, to preserve its optimal properties.


The primary application of 2-[1-(Mercaptomethyl)cyclopropyl]acetic Acid is its use as a crucial intermediate in the synthesis of Montelukast (CAS: 158966-92-8). Montelukast, a leukotriene D4-receptor antagonist, is widely prescribed for the long-term treatment of asthma and for relieving symptoms of allergic rhinitis. Its efficacy in managing respiratory conditions underscores the importance of high-quality intermediates like 2-[1-(Mercaptomethyl)cyclopropyl]acetic Acid in the pharmaceutical supply chain.
