The pharmaceutical industry's advancement is deeply rooted in the precise synthesis of complex drug molecules. Rosuvastatin Calcium, a widely prescribed statin for managing cholesterol, is a prime example of such a molecule. Its efficacy and safety are directly linked to the quality of its precursors. Among the essential building blocks for Rosuvastatin Calcium is S-Methyl-Isothiourea Hydrochloride (CAS: 53114-57-1). This article explores the chemical significance of this intermediate and its indispensable contribution to modern pharmaceutical manufacturing.

S-Methyl-Isothiourea Hydrochloride: A Chemical Overview

S-Methyl-Isothiourea Hydrochloride, identified by CAS number 53114-57-1, is a white powder characterized by its molecular formula C2H7ClN2S and a molecular weight of 126.60800. Industrially, it is known for its high purity, typically exceeding 98.0%. Its physical properties, such as a density of 1.26 g/cm³ and a boiling point of 138.8°C, are important considerations for its handling and integration into synthesis processes. Proper storage conditions, including tightly closed containers in a cool, dry, and well-ventilated area, are vital to maintain its chemical integrity.

The Synthesis Pathway of Rosuvastatin Calcium

The creation of Rosuvastatin Calcium is a multi-step process that requires meticulous control over chemical reactions and the use of high-purity intermediates. S-Methyl-Isothiourea Hydrochloride plays a pivotal role by contributing a specific functional group or structural component that is essential for forming the final drug molecule. While the exact proprietary synthesis routes may vary between manufacturers, the fundamental requirement for this specific isothiourea derivative remains constant.

The importance of using high-purity S-Methyl-Isothiourea Hydrochloride cannot be overstated. Impurities in intermediates can lead to unwanted side reactions, reduced yields, and ultimately, a final drug product that may not meet stringent regulatory and therapeutic standards. Therefore, pharmaceutical manufacturers actively seek suppliers who can guarantee lot-to-lot consistency and adherence to pharmaceutical-grade specifications for this crucial intermediate.

Procurement and Supply Chain Considerations

For pharmaceutical companies needing to buy S-Methyl-Isothiourea Hydrochloride, partnering with a reliable manufacturer is key.
