The development of targeted cancer therapies has revolutionized patient care, and Bortezomib stands as a prime example of a successful proteasome inhibitor. For pharmaceutical manufacturers and R&D teams involved in the synthesis of Bortezomib, understanding the critical role of its intermediates is paramount. Among these, (1S,2S,3R,5S)-(+)-2,3-Pinanediol (CAS: 18680-27-8) is a key chiral building block whose quality and availability directly impact the efficiency and success of the overall synthesis.

What is Bortezomib?

Bortezomib, marketed under brand names like Velcade, is a cancer medication used to treat multiple myeloma and mantle cell lymphoma. It functions by inhibiting proteasomes, cellular complexes responsible for protein degradation, thereby disrupting cell cycle progression and inducing apoptosis in cancer cells. The complex molecular structure of Bortezomib necessitates precise stereochemical control during its synthesis, making chiral intermediates indispensable.

The Importance of (1S,2S,3R,5S)-(+)-2,3-Pinanediol

(1S,2S,3R,5S)-(+)-2,3-Pinanediol is a bicyclic monoterpene diol derived from alpha-pinene. Its specific stereochemical configuration makes it an ideal chiral auxiliary or building block for constructing the intricate stereocenters present in Bortezomib. The high purity (typically ≥99.0%) of this intermediate is critical to ensure that the final active pharmaceutical ingredient (API) possesses the correct three-dimensional structure, which is fundamental for its biological activity and therapeutic efficacy. Impurities or incorrect stereoisomers can lead to reduced efficacy or, worse, harmful side effects.

Reliable Sourcing for Pharmaceutical Manufacturing

For pharmaceutical companies, sourcing (1S,2S,3R,5S)-(+)-2,3-Pinanediol requires a dependable partner who can guarantee consistent quality and a secure supply chain. When you decide to buy this intermediate, it is essential to partner with a manufacturer that adheres to strict quality control standards. Look for suppliers who can provide:

  • Certificates of Analysis (COA) detailing purity and stereochemical integrity.
  • Detailed Safety Data Sheets (SDS).
  • Consistent batch-to-batch quality.
  • Reliable delivery schedules to meet production demands.
  • Competitive pricing without compromising on quality.
